Principle of Relay Protection Tester
Its principle is to simulate various normal and fault states of the power system, applying precisely controllable three-phase current and three-phase voltage signals to the protection device under test (such as relays and protection devices). It is divided into two parts: the main loop and the auxiliary loop. As a core part of electric system reliability and safety, protective relays aid in preserving equipment and maintaining stability by isolating affected zones automatically via. The relay protection tester is an indispensable piece of equipment in power system testing; its core functions are designed to comprehensively verify the operational characteristics and reliability of relay protection devices under various operating conditions.
