Primary Injection Testing

Primary current injection testing is usually associated with high current and high voltage power distribution systems in electricity substations or in a large industrial installations. By injecting a predetermined current into the circuit breaker, it is possible to determine whether the relay will trip at this current and, if so, how long the current needs to flow before the trip is initiated. Primary current injection testing invaluable aid to faultfinding.
