Standard low-voltage earthing resistor cabinets typically include earthing transformers, resistors, intelligent controllers, and disconnect switches. These cabinets have seen continuous development and widespread application in the power industry. They are usually installed in power systems such as power plants. In the power supply systems of industrial and mining enterprises' transformation and distribution systems, the system operation method for selecting these low-voltage earthing resistor cabinets in the power grid has been completed.

The low-voltage earthing resistor cabinet, also known as the resistor cabinet, is installed between the transformer neutral point or generator neutral point and the ground. The international and domestic industry standards are the same.

Each solution for a low-voltage grounding resistor cabinet must be meticulously designed, requiring the expertise of the technical staff at the manufacturing facility. The low-voltage grounding resistor cabinet is used at the neutral point of transformers, possibly also at the neutral point of generators and ground, with international and domestic industry standards being consistent. When the grounding current is 3A or more, it is typically necessary to install a resistor cabinet at the neutral point to provide maintenance benefits for the main transformer or generator.
