Due to their critical role in the power system, protective relays should be acceptance tested prior to being placed in service and periodically thereafter to ensure reliable performance. In a normal industrial application, periodic testing should be done at least every 2 years in accordance with NFPA 70B 2016 (Recommended Practice for Electrical Equipment Maintenance).
Protective relay testing may be divided into three categories: acceptance testing, commissioning, and maintenance testing. Which of the procedures described below are added to your test plan will depend on the specific project or industry specifications, to be determined by the equipment owner or system engineer.
