Question { 4372 }

how to calculate the knee point voltage of current
transformer?


Answer


CT resistance = 1.8ohm,
Lead resistance = 4.0 ohm,
Starting current = 195*5/200 = 4.875 Amp
Starting voltage = 4.87(1.8+4)= 28.275 = 28.3 volts
This is to be set to 30Volt,

But please remember that knee voltage should be 60 volt
minimum.
