Difference between Live tank and dead tank current transformer
Before we start, lets go back to CT basics, what a CT does , obviously a 2000/1 amp delivers 1 amp at secondary when 2000 amp is flowing or 0.5…
Terms related to CT/PT(Burden, Accuracy Class, Instrument Safety factor, knee point voltage etc.)
There are many terms we come across when we read about current transformer(CT) and Potential transformer(PT) or voltage transformer(VT) /capacitive voltage transformer( CVT). below are meaning of these terms. CT/PT…
What is CVT(Capacitive Voltage Transformer)
The capacitive-coupled potential transformer (CCPT) or Capacitive Voltage Transformer is a Voltage Transformer with a capacitive circuit as shown in the figure below. The two Capacitor C1 and C2 here…
