Role of resistance cabinet
1. Resistance cabinet is widely used in generator neutral points to limit ground current to prevent harm of various overvoltage.
2. The neutral point can limit the fault current to the appropriate value through the resistor, and improve the sensitivity of relay protection to the trip, and simultaneously make the fault point may only occur local slight burns, limit the transient overvoltage to normal line voltage.2.6 times the neutral point voltage, restricting the reimbustion of the arc, preventing an arc gap over voltage corruption master device.
3. At the same time, it can effectively prevent the ferromagnetic resonant vapor, thereby ensuring the safe operation of the generator.Reduce the power grid overvoltage, improve the security, reliability, and good results.
