I guess I'm wondering about some rule of thumb numbers. I have a small diesel power plant feeding some other loads in addition to some single phase motors. We do have some trouble with starting the motors with volatge drop . I wondering about installing three phase motors. What will I save...
Which is easier to start ? A single phase phase motor of a given hp fed from a single phase generator at some voltage or a three phase motor of the same hp fed from a three phase generator of the same voltage.
Does it matter if the same single phase motor is fed from a three phase generator ?
I am looking at installing a recloser on diesel supplied distribution system. Can this be harmful to the diesel gensets to be opening an dclosing the line quick succession.
When a transformer manufacturer states full load and no load losses for a transformer does the full load loss number contain both copper and core losses such that you can subtract the no load loss from the full load loss to get the copper loss .
I'm wondering what the industry standard is for...
I read the following quote about autotransformers. " Abnormal volatges may occur in three-phase wye connected autotransformers due to either line grounds, third harmonics or line transients "
What is the reason behind this and can this occur because of a loss of phase ?
Does anyone know of a used shunt reactor that may be available? We require a replacement due to lightning damage and are having trouble locating used. Factory lead time is too long.<br><br>Specs:<br><br>250 Amp<br>29 Ohm<br>76 mH<br>1700 kVa<br><br>Or thereabouts<br>
