(1) Exciting Amperage
Amperage fluctuates based upon the winding temperature. Following is for reference only.
Frequency/Rated Output Load Exciting Amperage (Measured)
3-Phase 60Hz: 11kVA
No load 0.38A
Full load( power factor=1.0) 0.63A
(2) Resistance Value
Nominal resistance of the winding is tolerated within ± 10% at 32 °
F(

℃
) of the ambient
temperature.The resistance must be measured by low resistance tester. It can not be measured
by multi-purpose tester cause of index error.
