Type of earthing system

Question

Accepted Answer

The type of earthing system refers to the method used to connect electrical equipment to the ground for safety and functionality.

There are several types of earthing systems, including TN, TT, and IT systems.
TN systems have a direct connection between the neutral point of the transformer and the ground.
TT systems have a separate connection for the earth and neutral points, typically used for sensitive equipment.
IT systems have no direct connection to the ground, providing a high level of insulation but requiring regular testing.
The choice of earthing system depends on factors such as the location, equipment sensitivity, and safety requirements.
