As the operational lifespan of equipment increases, aging phenomena become more pronounced, leading to performance degradation, increased failure rates, and the potential inability of conventional tests to fully uncover latent problems. This article will delve into the impact of power equipment aging on relay protection testing and propose corresponding countermeasures.

Relay protection test instruments are used to verify and calibrate the performance of relay protection devices in the power system, and the reliability is directly related to the safe operation of the power system. In actual use, various abnormal phenomena may be encountered. These phenomena not only affect the accuracy of the test results, but also may cause device damage. This article will explore these abnormal phenomena and their treatment methods in detail, and analyze it in combination with actual cases.

Yesterday, our company successfully received noble customers from India and conducted a in -depth factory inspection event. During the one -day inspection factory, our company fully demonstrated the operation steps and performance characteristics of ground resistance tester, relay protection tester, and circuit breaker tester. The trip to the factory ended successfully in a pleasant atmosphere.

Relay maintenance equipment is required to respond to faults and abnormal operating conditions of electrical equipment, automatically, quickly and selectively act on circuit breakers, remove faulty equipment from the system, ensure that fault-free equipment continues to operate normally, and control the scale of accidents to a minimum, improve the reliability of system operation, and maximize the safe connection of power supply to users.

Recently, our company was delighted to receive good news, successfully securing orders for a total of three devices from new clients in Chile and Croatia. Among these, two are high-performance relay protection testers, and one is an advanced cable fault locator. This not only demonstrates our company’s competitiveness in the international market but also highlights the strength of our factory and our exceptional services.

Recently, we are honored to announce that one of our long-term partners, a power company from Vietnam, has purchased another RDJB-802M three-phase relay protection tester. This repurchase not only consolidates the cooperative relationship between the two parties but also further proves the competitiveness and brand reputation of our products in the international market.
