why ct secondary side shortlink provided? its open what will happen?while running ?..

Answer / shaikh

The current in the secondary side of a CT (Current Transformer) is induced by the current flowing in the primary circuit. If the current continues to flow in the primary circuit and the CT is left "Open Circuit" then dangerous voltages can build up and cause damage to equipment when reconnected or personal injury by electric shock.
Therefore, shorting the secondary terminals of the CT allows current to circulate taking flux with, thus reducing the building up of flux; the higher the flux the higher the emf (voltage) induced; E = Blv.

Answer / aamirali

Current Transformer (CT)is used for measurement, control and as a protection device. We make short ckt secondary of ct because we can measure the ratio and polarity of secondary side. if it isnt short cktd it will not operate under over current on secondary side.
