The ground grounding means that the neutral point of the power system and the electric device, the exposed conductive portion of the electric equipment and the external conductive portion of the device are connected to the ground via conductors. Can be divided into working ground, lightning protection ground and protection ground.

The working ground is set by the operation requirements of the power system (such as neutral point grounding), so that under normal conditions, current flows through the ground electrode for a long time, but the current is unbalanced by a few amperes to a few tens of amperes. When a system has a ground fault, thousands of amperes of working current flows through the grounding electrode, but the current is cut off within 0.05-0.1 s by the relay protection device, and even if the system is backup protection, the action is generally within 1 s.

Lightning protection earthing is earthing for eliminating dangerous influence of overvoltage, such as earthing of lightning rod, lightning conductor and lightning arrester. The lightning protection grounding can only flow current under the action of lightning impulse, the amplitude of the lightning current flowing through the lightning protection grounding electrode can reach dozens to hundreds of kiloamperes, but the duration is short.

The protective grounding is grounding which is arranged for preventing equipment from being endangered to personal safety due to insulation damage and electrification, such as a metal shell of power equipment, a reinforced concrete pole and a metal tower. The protective earth only allows the flow of current in the event of a breakdown of the insulation of the installation, the value of which can vary within wide limits.

The corresponding grounding terminal is needed to be used while grounding, the existing grounding terminal is a terminal for carrying out corresponding grounding, and the grounding process is complicated.
