Working principle of water resistance cabinet

Working principle: a special electrolyte is inserted in series into the rotor circuit of the wound motor as the resistance. By adjusting the concentration of the electrolyte and changing the distance between the two polar plates, the value of the series resistance always meets the requirements of... Read More

Building electrical – why should the neutral grounding point be selected for grounding resistance cabinet

The grounding resistance cabinet adopts neutral point grounding, which can reduce the transient overvoltage during single-phase grounding, eliminate the resonance overvoltage and arc grounding overvoltage, and the relay protection device can quickly select the fault line and cut off the fault poi...
