One and two-point method: This method is suitable for small grounding devices, such as metal pipe systems, and requires that the pipe joints have not been insulated and can only measure the resistance value of a single vertical ground pole. To measure the ground resistance using the two-point method, it is necessary to ensure that the resistance of the ground electrode to be measured is much larger than the resistance of the measured current electrode. The measurement results are the sum of the

First of all, we need to understand what the "simulated circuit breaker device" plays a role. The "simulated circuit breaker device" is mainly used for the entire set of tests of power system power failure protection devices or complete sets of relay protection screens, which can truly simulate the break-off time of the circuit breaker. . Simulate the tripping and closing of the high-voltage circuit breaker during the entire set of tests to avoid the adverse effects of repeated splits and closi
