Hi everyone!
According to IEC 60044-5/04, Clause 9.9.2 the test values of the actual primary voltage UP depend on the specified voltage factor FV in the equivalent circuit. I performed transient response test on the capacitor voltage transformer UPR=110000/*3 V, Us1=100/sqrt(3) V; 50 VA; 0,2, Us1=100/sqrt(3) V; 20 VA; 3P and FV=1,5.
Test was performed at UP =1,0xUPR, 1,2xUPR, 1,5xUPR because I wasn’t sure if the UP=1,5xUPR is the only necessary test voltage.
So, can this test be performed only at UP=1,5 UPR?
UPR-rated voltage
UP-actual primary voltage
Thank You!
