Generator Neutral Earthing resistor Cabinet/Grounding resistor bank
Generator Neutral Earthing resistor Cabinet/Grounding resistor bank
Introduction
The neutral point grounding through resistance has been applied to my country’s power distribution network system in the 1990s, and is currently widely used in my country’s urban power supply systems, power plants, railways, metallurgy and petrochemical systems, and is useful for improving the reliability and safety of system operations. Sex has a good effect.
