ZAI-RLC AC IMPEDANCE SIMULATION CABINET

Series:

The ZAI-RLC series microgrid cable impedance simulation system consists of cable line simulation impedance and overhead line simulation impedance. It can accurately simulate cable impedance parameters, and the cable length and specifications are customized according to user requirements. It corresponds to the impedance, inductive reactance, and capacitive reactance values of the microgrid access cable, and simulates the length of the connected common low-voltage power supply system cable, with a step of 50 meters (the step can be customized). It meets the needs of distributed power source experiment and testing, and is essential experimental equipment for developing and verifying relay protection programs.
