Why is power system grounding important?

Power system grounding is very important since most faults involve ground. Then, it has a basic role in the protection of its components as well as safety for the operator. There are a variety of grounding techniques utilized for mooring an electrical system to the ground. Let’s look at each type next.

What is system grounding?

Let’s look at each type next. System grounding refers to the limit of the defined values the voltage has to the ground in every part of the electrical system. It connects the current-carrying point of the electrical system to the ground, i.e., the neutral of transformers and rotating equipment as well as lines.

Why is grounding important?

Grounding has a key role in the correct operation of the electrical systems, either power or electronics, as well as protecting people. System grounding helps detect and clear ground faults. Equipment grounding provides a return path for ground-fault current. Bonding keeps electrical continuity and conductivity.

What is equipment grounding?

Equipment grounding connects all non-current-carrying metal parts of the wiring system or apparatus to the ground. Examples include the cabinet of the service equipment, the frames of transformers and motors, the metal conduit and boxes, the metal shield of shielded cables, poles, towers, and more.

What is lightning protection grounding?

Lightning protection grounding helps protect structures and equipment from direct strikes. Overhead ground wires and surge arresters, connected to ground, can limit dangerous system overvoltages to safe values. Fundamentally, grounding an electronic system is the same as grounding any electrical system.

What is neutral grounding?

It connects the current-carrying point of the electrical system to the ground, i.e., the neutral of transformers and rotating equipment as well as lines. The art and science of neutral grounding are of paramount importance in this analysis.
