High Voltage Switch Smart Circuit Breatker Simulation Device
The dual-circuit simulated circuit breaker places two sets of independent simulated circuit breakers in the same chassis, which can simulate the three-phase and split-phase operation of the circuit breaker, single trip coil or double trip coil circuit breaker, switch self-provided test, and switch cabinet tripping/rejection and other action behaviors. It is suitable for power systems, industrial and mining enterprises, scientific research, teaching colleges, etc., as a substitute for actual circuit breakers in relay protection and automatic device tests.

The methods for setting overvoltage protection of the P3 microcomputer protection device include: setting through the device panel buttons and setting with the Easergy Pro configuration software. Here, it mainly introduces how to use the buttons on the device panel for setting. For example, in the first stage of over - current protection, the voltage threshold U> is set to 1.2Un (Un is the rated value of the transformer), and the delay time is set to 0.5S.
