Abstract：This paper delves into the ground resistance testing methods within subway power lighting systems.Ground resistance plays a crucial role in ensuring electrical safety,system stability,and compliance.Moreover,anomalies in ground resistance can lead to increased risks of electrical fires,compromise system stability,and shorten the lifespan of equipment.Hence,effective testing methods are necessary.The article summarizes three primary ground resistance testing methods:the Angular Method,the Four-Point Method,and the Clamp-On Ground Resistance Tester Method,each adaptable to the specific needs of subway systems.
