The effective and efficient operation of a power grid is largely dependent on the relay scheme. The importance of this critical electrical component makes it essential to regularly test its health status using high-grade electrical test equipment.

When power system faults or systems are healthy problems don't occur and protection system may not operate for extended periods, therefore, a maintenance or testing program is necessary to determine the performance and availability of a protection system.

Protective relays do not generally perform until a fault or other power system problem requires that they operate to protect the power system elements. With a healthy power system faults or system problems don't occur, and the protection system may not operate for extended periods. A failure of the protection system to operate when needed can result in equipment damage, personnel hazards, and wide area disturbances or customer outages. This is why a maintenance or testing program is necessary to determine the performance and availability of a protection system.

The testing of high impedance electromechanical relays is a challenge for any test instrument. This is especially true if an over-current electromechanical relay is being used to detect ground or earth faults, one of the most critical and sensitive protections in the system. The ground over-current relays are relied on the most when everything else fails to detect a high resistance fault in the system, therefore it is vital to ensure that the ground over current relays are working correctly.

Conventional steady-state tests sets are only capable of testing each component of the system individually, therefore it becomes very difficult to predict the behavior of the entire system when subjected to true power system events. This results in performance uncertainties and could be the cause of misoperations.

Performing diagnostic tests on relays usually requires accurate test sets to ensure their safety. A false "pass" result can lead to serious problems in your electrical system. It is wise to rent a high quality test set to ensure reliable test results.
