Home / Microprocessor-based relay protection testing
Microprocessor based protective relays do require initial and then periodic testing and may very occasionally require maintenance. This may seem counterintuitive because there are (almost) no moving parts and no adjustments to make. On the contrary, testing with HIL provides flexibility and the ab lity to simulate complex scenarios without the risk associated with high currents and voltages. In the author's opinion in order to verify the proper operation of complex multifunctional microprocessor-based protection devices (MPD) at their inspection, start-up after repairs or during periodic tests there is no need to use the actual settings at which the relay is to be operated in a certain.
Perform commissioning, functional testing, and troubleshooting of protective relays (electromechanical, digital, microprocessor-based) for high-voltage substations and industrial electrical systems.
