Circuit Breaker Analysis Systems
-
When a fault such as a short circuit or current overload is detected by a protective relay, a trip impulse is sent to the circuit breaker. The circuit breaker must function as specified and interrupt the current as soon as possible or severe damage may occur. The damage caused by a malfunctioning circuit breaker can often be catastrophic, resulting in significant damage to the electrical system.

Primary Current Injection Testers
-
Primary Current Injection Tester is designed for testing protective relay and circuit breakers and also testing the turns ratio of current transformers at high variable currents. A test current is injected into the primary side of a system to determine how the system behaves at particular levels of current. This test makes it possible to determine whether the relay will trip and how long the current needs to flow before the trip is initiated.
