For checking circuit breaker and protective relay systems, the secondary injection test set is the main piece of electrical test equipment for companies to use. It differs from the standard primary injection testing method in that there is no current flowing and contacts remain closed during the testing process.
Because trip units serve a critical role in electrical systems, companies must actively test them to prevent electrical faults from causing equipment failure or accidents. Secondary injection tests pinpoint any defects in the trip unit or other protective systems ensuring that systems are functioning normally.
Protec offers a large inventory of Secondary Injection Test Sets available for rent, lease or purchase all at affordable rates.
