A relay protection tester is a device used to test and verify the performance of relay protection devices in power systems. The main purpose of the power-swing blocking function is to differentiate faults from power swings and block distance or other relay elements from operating during stable or unstable power swings. Megger's smart relay testing solutions and expert support help you validate protection performance, improve system reliability, and ensure continuity of power across your network.
