Relay protection test is an essential part of power system maintenance. It helps in identifying the performance of protective relays used in power systems. The secondary current injection method is commonly used in the relay protection test. However, to ensure accurate results, the use of a Relay Protection Tester is crucial.
A Relay Protection Tester is an advanced testing machine used for relay protection testing. It is a portable device that can simulate many different faults and abnormal conditions that may occur in a power system. The device generates test signals to stimulate relays so that their performance can be measured and analyzed. The tester can measure the parameters such as operating time, tripping current, and reset characteristics of the tested relays.
The 3 phase relay tester adopt Four phase voltage, three phase current output. It is widely used in power systems testing due to its ability to test three-phase relays at once. The 3-phase relay tester is also equipped with an ability to test phase-to-phase and phase-to-ground faults. This feature makes it an indispensable tool for testing any three-phase relay protection scheme. Not only the traditional relay and protection devices can be tested, but also a variety of modern computer protection tests, especially for transformer differential power protection and self-throwing devices, the test is more convenient and perfect.
The 6-phase relay tester is also an advanced relay protection tester that has the ability to simulate a 6-phase power system. It adopts Six-phase voltage, and six-phase current output. It is designed to test complicated and advanced protection schemes such as distance protection, transformation differential protection, and high impedance protection. It is a versatile tool that can perform both voltage and current testing.
The use of the 3-phase relay tester and the 6-phase relay tester has become increasingly important in modern power systems testing due to their versatile functionality and ability to test advanced protection schemes.
