1. It is composed of special high-power zinc oxide nonlinear resistors in series and parallel, which has the advantages of small size, stable performance and strong flow capacity
2. Equipped with a microcomputer control system, which provides convenience for the gradual reduction of the grounding resistance required by the expansion of the power grid in the later stage
3. It can be operated in parallel with resistance or reactance, which provides convenience for the gradual reduction of grounding resistance required for later grid expansion.
4. When the transformer winding is connected in delta and the Z-type winding grounding transformer needs to be installed independently, this device is used together with it.
5. It can reduce the overvoltage of the non-faulty phase and various operating voltages when single-phase grounding, suppress arc grounding overvoltage, eliminate resonance overvoltage and disconnection overvoltage
6. It can maintain operation when single-phase ground fault occurs, and the operation mode is flexible, which can meet different operation requirements
7. The overvoltage level is low, and the single-phase ground fault develops into the probability pole of phase-to-phase short circuit, which improves the operating conditions of electrical equipment and ensures the safety of electrical equipment with low insulation level in the power grid.
8. The application range of the capacitance current change is relatively large, simple, reliable and economical
9. Use high-quality non-metal special materials or stainless steel alloy grid resistors, with good electrical conductivity. Resistance can withstand high temperature of 1400 ℃, corrosion resistance, high protection level
10. The product can add a grounding recording device to record the number of times the grounding resistance is grounded
