Relay Protection Tester onlly

The ONLLY Relay Protection Tester ONLLY-AT1266-40AH is an advanced and highly reliable testing device specifically designed for testing relay protection systems in electrical networks, substations, and power plants. A relay protection tester is a device used to test and verify the performance of relay protection devices in power systems. Testing protection systems doesn't stop at the relay. It's ideal for power plants, substations, equipment manufacturers, and institutions needing relay protection evaluations. Versatile Outputs: Supports up to 6-phase voltage/current. The instrument has standard four phase voltage and three-phase current output. It can not only test various traditional relays and protection devices, but also test various modern microcomputer protection, especially for transformer differential power protection and standby automatic switching.
