The PICU-1000 is a versatile Primary Injection Test Instrument designed for reliable testing and commissioning of high-current protection systems. With an output capacity of up to 1000 Amperes, it ensures accurate performance verification of protective devices and current transformers in power utilities, industries, and testing facilities.

Applications

  • Timing Tests of Protective Relay through primary injection.
  • Timing Tests of MCCBs and other circuit protection devices.
  • Measurement of Current Transformer Turns Ratio (CTTR)

Protective Relay Timing Tests

The PICU-1000 is capable of performing timing tests on protective relays by injecting high primary currents and accurately measuring the relay's operating time. By supplying the required fault-level current and monitoring the relay's trip contact response, the PICU-1000 enables precise verification of relay pickup and operating characteristics in line with time–current curves.

MCCB Testing

The PICU-1000 provides a reliable method for testing Moulded Case Circuit Breakers (MCCBs) under primary injection conditions. By delivering the required high current, it allows verification of breaker tripping performance, including long-time, short-time, and instantaneous trip characteristics, ensuring MCCBs operate within their specified protection parameters.

Current Transformer Turns Ratio Testing

With its high-current injection capability, the PICU-1000 can also be used to verify the turns ratio and polarity of Current Transformers (CTs). By applying a controlled current to the primary side and measuring the corresponding secondary output, it ensures CTs maintain accuracy and reliability in protection and metering applications.
