HPT Type protection current transformer

Introduce:

Protection current transformer measures the large current of the alternating current, it needs to be converted into a relatively uniform current for the convenience of the secondary instrument measurement.
Whether the current transformer can correctly transfer the primary current in the short-circuit transition process plays a decisive role in the correct action of the relay protection.
The protective current transformer mainly cooperates with the relay protection device, and provides a signal to the relay device to cut off the faulty circuit when a fault occurs in the line, so as to protect the safety of the power system.

Features:

  • Shell is made of flame-retardant, 140 temperature-resistant polycarbonate injection molding.
  • The iron core is made of directional cold rolled silicon steel strip.
  • The secondary conductor is high-strength electromagnetic enameled wire.
  • The product structure is novel, beautiful in appearance, easy to install,small in size, light in weight, high in accuracy, and large in capacity.

Applications:

  • It is used to collect low voltage overload and short-circuit signals, and is used with protection relays.
  • The primary measurement range is 200-6300A, and the secondary output is 5A, 1A. class:5P5,5P10,5P15,5P20
  • Collect low-voltage overload and short-circuit signals, which can be used in conjunction with the motor protection unit.
  • Used in places where there is no direct rain or snow, no serious pollution and severe vibration.
