Overvoltage Protector for Current-Transformer Protection

CCTP-03

When the power system is in operation, the secondary side of the current transformer is designed to prevent it from allowing an open circuit.

Open circuits can be the result of lightning strikes, harmonic oscillation over current, capacity charge current or other events which may result in extreme high voltage causing damage to the current transformer and secondary equipment, or even posing a threat to personal safety.

Our current transformer secondary over voltage protector CCTP-03 is there to prevent accidents that are the result of abnormal secondary high voltage.

Current Transformer (CT) Overvoltage Protector

Product Features

  • Our CCTP-03 series is safety tested and assured.
  • With a reset key on the operating panel, the circuit can be returned to normal and the voltage protector goes back into standard operating status.
  • It is programmable with a digital display setting for voltage and time.
  • It comes with a 3 phase current detectable LED signal and a visible power on light.
  • Can be supplied for over current winding, measurement winding, differential winding, bus protection winding and alternate winding of the secondary current transformer.
