FAQ
Q: What is the primary current injection set?
A: A primary current injection set is the preferred method for testing circuit breakers, incorporating current sensors, wiring, and the breaker’s current conduction path. However, it may not consistently identify sensor wiring and polarity issues, presenting limitations.
Q: What is the difference between primary and secondary current injection test sets?
A: Primary and secondary current injection test sets differ in their testing approaches. The primary injection test set measures trip time by injecting a multiple of the fault-rated current through the breaker. Conversely, the secondary injection test set measures trip time by injecting a fault-rated current ratio into the trip unit.
Q: How do you do a primary injection test?
A: To perform a primary injection test:
1. Isolate Breaker: Disconnect from the system.
2. Connect Test Set: Use the primary injection test set.
3. Inject Current: Introduce high current.
4. Measure Trip Time: Record the time to trip.
5. Evaluate and Repeat: Analyze results and repeat if needed.
6. Prioritize Safety: Follow safety protocols.
7. Document: Record test data and outcomes.
Q: What is the purpose of the primary injection kit?
A: The primary injection kit tests and validates the performance of circuit breakers and protective devices. It injects a high current, simulating fault conditions, to assess the breaker’s response and ensure its proper functioning under real-world scenarios. This kit is essential for verifying the reliability and accuracy of protective systems in electrical networks.
