Apa yang di maksud dengan Generator Set ?
Genset atau kepanjangan dari generator set adalah sebuah perangkat yang telah berfungsi dapat menghasilkan daya listrik. Disebut sebagai generator set dengan pengertian adalah satu set peralatan yang tergabung dari dua perangkat yang berbeda yaitu engine dan generator atau alternator. Engine sebagai perangkat pemutar sedangkan generator atau alternator sebagai perangkat pembangkit listrik.
Engine juga dapat berupa perangkat mesin diesel berbahan bakar solar atau mesin berbahan bakar bensin, sedangkan generator atau alternator juga merupakan kumparan atau gulungan tembaga yang telah terdiri dari stator ( kumparan statis ) dan rotor (kumparan berputar).
Dalam ilmu fisikia yang sederhana juga dapat dijelaskan bahwa engine dapat memutar rotor pada generator sehingga timbul medan magnit pada kumparan stator generator, medan magnit yang timbul pada stator dan berinteraksi dengan rotor yang berputar akan dapat menghasilkan arus listrik sesuai hukum Lorentz (ingat pelajaran fisika SMA dulu).
Arus listrik yang telah dihasilkan oleh generator akan memiliki perbedaan tegangan di antara kedua kutub generatornya sehingga apabila dihubungkan dengan beban akan menghasilkan daya listrik, atau dalam rumusan fisika sebagai
P (daya) = V (tegangan) x I (arus),
dengan satuan adalah VA atau Volt Ampere.
Rumusan fisika yang lebih kompleks lagi dijelaskan bahwa
P (daya) = V (tegangan) x I (arus) x CosPhi (faktor daya) dengan satuan Watt.
Apa saja type genset?
Genset juga dapat dibedakan dari jenis engine penggeraknya, dimana kita kenal tipe-tipe engine yaitu engine diesel dan engine non diesel /bensin. Engine diesel telah dikenali dari bahan bakarnya yang berupa solar, sedangkan engine non diesel berbahan bakar bensin premium.
Di pasaran, genset dengan engine non diesel atau berbahan bakar bensin biasa diaplikasikan pada genset yang berkapasitas kecil atau dalam kapasitas maksimum 10.000 VA atau 10 kVA, sedangkan genset diesel berbahan bakar solar diaplikasikan pada genset berkapasitas > 10 kVA. Mengapa demikian ? Hal tersebut terkait dengan tenaga yang telah dihasilkan oleh diesel lebih besar daripada engine non diesel, dimana cara kerja pembakaran diesel yang lebih sederhana yaitu tanpa busi, lebih hemat dalam pemeliharaan, lebih responsif dan bertenaga. Selain itu untuk aplikasi industri dimana bahan bakar diesel (solar) lebih murah daripada bensin (gasoline). Tulisan lebih dalam tentang cara kerja engine diesel akan kami sajikan dalam tulisan-tulisan berikutnya.
Dalam aplikasi kita akan jumpai bahwa genset yang terdiri dari genset 1 phasa atau 3 phasa, apa artinya ini ? Kita akan jelaskan lebih dalam lagi, bahwa pengertian 1 phasa atau 3 phasa adalah telah merujuk pada kapasitas tegangan yang telah dihasilkan oleh genset tersebut. Tegangan 1 phasa artinya tegangan yang telah dibentuk dari kutub L yang mengandung arus dengan kutub N yang tidak berarus, atau berarus Nol atau sering kita kenal sebagai Arde atau Ground. Sedangkan tegangan 3 phase telah dibentuk dari dua kutub yang bertegangan. Genset tiga phasa dapat menghasilkan tiga kali kapasitas genset 1 phasa. Pada sistem kelistrikan PLN kita, kapasitas 3 phasa yang dihasilkan untuk aplikasi rumah tangga adalah 380 Volt, sedangkan kapasitas 1 phasa adalah 220 Volt.
Daya listrik dalam ilmu fisika juga merupakan besaran vektor, artinya besaran yang telah memiliki besar dan arah, tegangan dan arus yang telah dihasilkan juga merupakan gelombang sinusoidal dengan frekuensi tertentu. Di Indonesia, frekuensi tegangan dan arus telah ditetapkan sebesar 50 Hz, dimana hal ini mengikuti standar frekuensi di Belanda atau negara-negara Eropa, sedangkan di negara Amerika Serikat dan Kanada menggunakan frekuensi 60 Hz.

Advertisement Politics Obama Finds a Bolder Voice on Race Issues
As he reflected on the festering wounds deepened by race and grievance that have been on painful display in America’s cities lately, President Obama on Monday found himself thinking about a young man he had just met named Malachi.
A few minutes before, in a closed-door round-table discussion at Lehman College in the Bronx, Mr. Obama had asked a group of black and Hispanic students from disadvantaged backgrounds what could be done to help them reach their goals. Several talked about counseling and guidance programs.
“Malachi, he just talked about — we should talk about love,” Mr. Obama told a crowd afterward, drifting away from his prepared remarks. “Because Malachi and I shared the fact that our dad wasn’t around and that sometimes we wondered why he wasn’t around and what had happened. But really, that’s what this comes down to is: Do we love these kids?”
Many presidents have governed during times of racial tension, but Mr. Obama is the first to see in the mirror a face that looks like those on the other side of history’s ledger. While his first term was consumed with the economy, war and health care, his second keeps coming back to the societal divide that was not bridged by his election. A president who eschewed focusing on race now seems to have found his voice again as he thinks about how to use his remaining time in office and beyond.
In the aftermath of racially charged unrest in places like Baltimore, Ferguson, Mo., and New York, Mr. Obama came to the Bronx on Monday for the announcement of a new nonprofit organization that is being spun off from his White House initiative called My Brother’s Keeper. Staked by more than $80 million in commitments from corporations and other donors, the new group, My Brother’s Keeper Alliance, will in effect provide the nucleus for Mr. Obama’s post-presidency, which will begin in January 2017.
“This will remain a mission for me and for Michelle not just for the rest of my presidency but for the rest of my life,” Mr. Obama said. “And the reason is simple,” he added. Referring to some of the youths he had just met, he said: “We see ourselves in these young men. I grew up without a dad. I grew up lost sometimes and adrift, not having a sense of a clear path. The only difference between me and a lot of other young men in this neighborhood and all across the country is that I grew up in an environment that was a little more forgiving.”
Organizers said the new alliance already had financial pledges from companies like American Express, Deloitte, Discovery Communications and News Corporation. The money will be used to help companies address obstacles facing young black and Hispanic men, provide grants to programs for disadvantaged youths, and help communities aid their populations.
Joe Echevarria, a former chief executive of Deloitte, the accounting and consulting firm, will lead the alliance, and among those on its leadership team or advisory group are executives at PepsiCo, News Corporation, Sprint, BET and Prudential Group Insurance; former Secretary of State Colin L. Powell; Senator Cory Booker, Democrat of New Jersey; former Attorney General Eric H. Holder Jr.; the music star John Legend; the retired athletes Alonzo Mourning, Jerome Bettis and Shaquille O’Neal; and the mayors of Indianapolis, Sacramento and Philadelphia.
The alliance, while nominally independent of the White House, may face some of the same questions confronting former Secretary of State Hillary Rodham Clinton as she begins another presidential campaign. Some of those donating to the alliance may have interests in government action, and skeptics may wonder whether they are trying to curry favor with the president by contributing.
“The Obama administration will have no role in deciding how donations are screened and what criteria they’ll set at the alliance for donor policies, because it’s an entirely separate entity,” Josh Earnest, the White House press secretary, told reporters on Air Force One en route to New York. But he added, “I’m confident that the members of the board are well aware of the president’s commitment to transparency.”
The alliance was in the works before the disturbances last week after the death of Freddie Gray, the black man who suffered fatal injuries while in police custody in Baltimore, but it reflected the evolution of Mr. Obama’s presidency. For him, in a way, it is coming back to issues that animated him as a young community organizer and politician. It was his own struggle with race and identity, captured in his youthful memoir, “Dreams From My Father,” that stood him apart from other presidential aspirants.
But that was a side of him that he kept largely to himself through the first years of his presidency while he focused on other priorities like turning the economy around, expanding government-subsidized health care and avoiding electoral land mines en route to re-election.
After securing a second term, Mr. Obama appeared more emboldened. Just a month after his 2013 inauguration, he talked passionately about opportunity and race with a group of teenage boys in Chicago, a moment aides point to as perhaps the first time he had spoken about these issues in such a personal, powerful way as president. A few months later, he publicly lamented the death of Trayvon Martin, a black Florida teenager, saying that “could have been me 35 years ago.”
That case, along with public ruptures of anger over police shootings in Ferguson and elsewhere, have pushed the issue of race and law enforcement onto the public agenda. Aides said they imagined that with his presidency in its final stages, Mr. Obama might be thinking more about what comes next and causes he can advance as a private citizen.
That is not to say that his public discussion of these issues has been universally welcomed. Some conservatives said he had made matters worse by seeming in their view to blame police officers in some of the disputed cases.
“President Obama, when he was elected, could have been a unifying leader,” Senator Ted Cruz of Texas, a Republican candidate for president, said at a forum last week. “He has made decisions that I think have inflamed racial tensions.”
On the other side of the ideological spectrum, some liberal African-American activists have complained that Mr. Obama has not done enough to help downtrodden communities. While he is speaking out more, these critics argue, he has hardly used the power of the presidency to make the sort of radical change they say is necessary.
The line Mr. Obama has tried to straddle has been a serrated one. He condemns police brutality as he defends most officers as honorable. He condemns “criminals and thugs” who looted in Baltimore while expressing empathy with those trapped in a cycle of poverty and hopelessness.
In the Bronx on Monday, Mr. Obama bemoaned the death of Brian Moore, a plainclothes New York police officer who had died earlier in the day after being shot in the head Saturday on a Queens street. Most police officers are “good and honest and fair and care deeply about their communities,” even as they put their lives on the line, Mr. Obama said.
“Which is why in addressing the issues in Baltimore or Ferguson or New York, the point I made was that if we’re just looking at policing, we’re looking at it too narrowly,” he added. “If we ask the police to simply contain and control problems that we ourselves have been unwilling to invest and solve, that’s not fair to the communities, it’s not fair to the police.”
Moreover, if society writes off some people, he said, “that’s not the kind of country I want to live in; that’s not what America is about.”
His message to young men like Malachi Hernandez, who attends Boston Latin Academy in Massachusetts, is not to give up.
“I want you to know you matter,” he said. “You matter to us.”
Rhapsody, a Lofty Literary Journal, Perused at 39,000 Feet
Last summer at a writers’ workshop in Oregon, the novelists Anthony Doerr, Karen Russell and Elissa Schappell were chatting over cocktails when they realized they had all published work in the same magazine. It wasn’t one of the usual literary outlets, like Tin House, The Paris Review or The New Yorker. It was Rhapsody, an in-flight magazine for United Airlines.
It seemed like a weird coincidence. Then again, considering Rhapsody’s growing roster of A-list fiction writers, maybe not. Since its first issue hit plane cabins a year and a half ago, Rhapsody has published original works by literary stars like Joyce Carol Oates, Rick Moody, Amy Bloom, Emma Straub and Mr. Doerr, who won the Pulitzer Prize for fiction two weeks ago.
As airlines try to distinguish their high-end service with luxuries like private sleeping chambers, showers, butler service and meals from five-star chefs, United Airlines is offering a loftier, more cerebral amenity to its first-class and business-class passengers: elegant prose by prominent novelists. There are no airport maps or disheartening lists of in-flight meal and entertainment options in Rhapsody. Instead, the magazine has published ruminative first-person travel accounts, cultural dispatches and probing essays about flight by more than 30 literary fiction writers.
An airline might seem like an odd literary patron. But as publishers and writers look for new ways to reach readers in a shaky retail climate, many have formed corporate alliances with transit companies, including American Airlines, JetBlue and Amtrak, that provide a captive audience.
Mark Krolick, United Airlines’ managing director of marketing and product development, said the quality of the writing in Rhapsody brings a patina of sophistication to its first-class service, along with other opulent touches like mood lighting, soft music and a branded scent.
“The high-end leisure or business-class traveler has higher expectations, even in the entertainment we provide,” he said.
Some of Rhapsody’s contributing writers say they were lured by the promise of free airfare and luxury accommodations provided by United, as well as exposure to an elite audience of some two million first-class and business-class travelers.
“It’s not your normal Park Slope Community Bookstore types who read Rhapsody,” Mr. Moody, author of the 1994 novel “The Ice Storm,” who wrote an introspective, philosophical piece about traveling to the Aran Islands of Ireland for Rhapsody, said in an email. “I’m not sure I myself am in that Rhapsody demographic, but I would like them to buy my books one day.”
In addition to offering travel perks, the magazine pays well and gives writers freedom, within reason, to choose their subject matter and write with style. Certain genres of flight stories are off limits, naturally: no plane crashes or woeful tales of lost luggage or rude flight attendants, and nothing too risqué.
“We’re not going to have someone write about joining the mile-high club,” said Jordan Heller, the editor in chief of Rhapsody. “Despite those restrictions, we’ve managed to come up with a lot of high-minded literary content.”
Guiding writers toward the right idea occasionally requires some gentle prodding. When Rhapsody’s executive editor asked Ms. Russell to contribute an essay about a memorable flight experience, she first pitched a story about the time she was chaperoning a group of teenagers on a trip to Europe, and their delayed plane sat at the airport in New York for several hours while other passengers got progressively drunker.
“He pointed out that disaster flights are not what people want to read about when they’re in transit, and very diplomatically suggested that maybe people want to read something that casts air travel in a more positive light,” said Ms. Russell, whose novel “Swamplandia!” was a finalist for the 2012 Pulitzer Prize.
She turned in a nostalgia-tinged essay about her first flight on a trip to Disney World when she was 6. “The Magic Kingdom was an anticlimax,” she wrote. “What ride could compare to that first flight?”
Ms. Oates also wrote about her first flight, in a tiny yellow propeller plane piloted by her father. The novelist Joyce Maynard told of the constant disappointment of never seeing her books in airport bookstores and the thrill of finally spotting a fellow plane passenger reading her novel “Labor Day.” Emily St. John Mandel, who was a finalist for the National Book Award in fiction last year, wrote about agonizing over which books to bring on a long flight.
“There’s nobody that’s looked down their noses at us as an in-flight magazine,” said Sean Manning, the magazine’s executive editor. “As big as these people are in the literary world, there’s still this untapped audience for them of luxury travelers.”
United is one of a handful of companies showcasing work by literary writers as a way to elevate their brands and engage customers. Chipotle has printed original work from writers like Toni Morrison, Jeffrey Eugenides and Barbara Kingsolver on its disposable cups and paper bags. The eyeglass company Warby Parker hosts parties for authors and sells books from 14 independent publishers in its stores.
JetBlue offers around 40 e-books from HarperCollins and Penguin Random House on its free wireless network, allowing passengers to read free samples and buy and download books. JetBlue will start offering 11 digital titles from Simon & Schuster soon. Amtrak recently forged an alliance with Penguin Random House to provide free digital samples from 28 popular titles, which passengers can buy and download over Amtrak’s admittedly spotty wireless service.
Amtrak is becoming an incubator for literary talent in its own right. Last year, it started a residency program, offering writers a free long-distance train trip and complimentary food. More than 16,000 writers applied and 24 made the cut.
Like Amtrak, Rhapsody has found that writers are eager to get onboard. On a rainy spring afternoon, Rhapsody’s editorial staff sat around a conference table discussing the June issue, which will feature an essay by the novelist Hannah Pittard and an unpublished short story by the late Elmore Leonard.
“Do you have that photo of Elmore Leonard? Can I see it?” Mr. Heller, the editor in chief, asked Rhapsody’s design director, Christos Hannides. Mr. Hannides slid it across the table and noted that they also had a photograph of cowboy spurs. “It’s very simple; it won’t take away from the literature,” he said.
Rhapsody’s office, an open space with exposed pipes and a vaulted brick ceiling, sits in Dumbo at the epicenter of literary Brooklyn, in the same converted tea warehouse as the literary journal N+1 and the digital publisher Atavist. Two of the magazine’s seven staff members hold graduate degrees in creative writing. Mr. Manning, the executive editor, has published a memoir and edited five literary anthologies.
Mr. Manning said Rhapsody was conceived from the start as a place for literary novelists to write with voice and style, and nobody had been put off that their work would live in plane cabins and airport lounges.
Still, some contributors say they wish the magazine were more widely circulated.
“I would love it if I could read it,” said Ms. Schappell, a Brooklyn-based novelist who wrote a feature story for Rhapsody’s inaugural issue. “But I never fly first class.”
