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.
Whether you are testing electromechanical relays or state-of-the-art designs, Doble diagnostic equipment can assist with verifying protection and control circuits and simulate system conditions. This equipment is modular and customizable for any testing program in order to adhere to a company’s practices and procedures, while meeting regulatory requirements.
