The 480 measurement is before we go through two transformers - 480 to 4200 and then 4200 to 42k. Our synchronous 2mw generators runs at 4200 but is currently off line for lack of water.
I might add that field coil temperatures are in the 165 to 170 F. range. So, is the low power factor simply...
Nameplate voltage is 480
Operating voltage is 480 +/- and is determined by grid voltage
Current on generator leads are 225 amps
Current on grid leads are 128 amps
Current on capacitor leads are 167 amps
Power factor on generator leaks is .57
Power factor on grid leads is .98
Rated output is...
It's not a wound but a squirrel cage rotor. It just seems to me that .57 is an awfully low power factor (name plate is .80) and I'm trying to learn why.
The unit was not operational when we purchased the plant due to a short caused by water infiltration, but as I recall, there were...
The turbine and asychronous generator are totaly submerged and the capacitor bank is not. Current between generator and capacitors is 225 amps, however power factor correction with capacitors reduces this to 128 amps going to the grid. A better generator power factor would reduce the reactive...
I have a water turbine driven submerged 100kw induction generator that was rewound a couple of years ago. Power factor is running at .57 which we are correcting with capacitors, however the high current between generator and capacitors is causing heat problems.
The field connections are 12...
