The full form of NGR is Neutral Grounding Resistor.
Neutral Grounding Resistor Explained
A Neutral Grounding Resistor (NGR) is a crucial component in electrical power systems. Its primary function, as the reference material states, is to limit ground fault currents to safe levels. This protection safeguards all the electrical equipment within the power system. NGRs are also known by other names:
- Neutral Earthing Resistors
- Earth Fault Protection Resistors
Why Use an NGR?
Here are some reasons why Neutral Grounding Resistors are important:
- Limiting Fault Current: NGRs prevent excessive current flow during ground faults.
- Equipment Protection: By limiting fault currents, NGRs protect electrical equipment from damage.
- Personnel Safety: Reduced fault currents enhance safety for personnel working with electrical systems.
