It is designed with user friendly features to check operations of protection component system including Current transformer, Circuit Breaker, current sensor & relays etc. The Motwane PIK with high VA burden makes it possible to deliver desired current to high impedance object like Current transformer. It has optional feature to measure CT secondary current as well as polarity.
Features
- Variable output current
- High VA burden to test high impedance objects
- Digital timer for measuring tripping time
- Zero start interlock for safety
- Auto cutoff upon tripping relay
- Current range ( Low – 50% & High – 100% of full range )
- CT sec current measurement
- CT polarity detection
- Wheel mounted for easy transportation
Application
The primary current injection method is usually the preferred method to verify the current sensors, wiring, and the current conduction path in the breaker. In order to identify sensor and wiring-related problems, it is recommended that the primary current injection test be conducted separately on each phase through current transformer which ensures that the sensors and wiring of the breaker are working proper.
The Primary current injection method is also useful for testing current transformer ratio. The secondary current of the transformer bears a known relationship with the primary current. Any change in the primary current is reflected in the secondary circuit. To verify the turns ratio and polarity tests on CT, current is injected on primary side of CT and measured at the secondary side for relaying and to ensure that they have the correct turn’s ratio and relaying accuracy.
High current injection (Primary current) is used and recommended during commissioning of protection systems. It is also recommended during major repairs and component replacement in power substations.
Motwane makes Primary Current Injection Kits are used to test Current Transformers, Circuit Breakers, Bus Bars, Relays, MCBs, MCCBs etc.
