Step Voltage Test
Step Voltage Test
(OP)
Hello All
I was taking a look of some reports about one test done with some instrument called EDA this one apply two different voltage to the windings, one is the half of rated voltage and the second is the rated voltages and analize many parameters includding Capacitance and PI values, in some history cases I can see the PI Value for the rated voltage (Usually 6 KV ) is less than the PI of the obtained at the half of rated voltaje so the PI decreases when Voltage raise. Any explanation about this ? wich other test could be done? power factor test could be good?
Thanks for the inputs
