Earth Fault Vs Earth Leakage (Arus Kerosakan Bumi Vs Arus Bocor Bumi)

 

Arus Kerosakan Bumi / Earth-fault current :

========

- Current flowing to earth due to an insulation fault.

- Arus yang bocor ke bumi apabila ada kegagalan penebat.

Arus Bocor Ke Bumi/ Earth-leakage current :

========

- Current flowing from the live parts to earth or extraneous conductive parts in the absence of an insulation fault.

- Arus bocor ke bumi yang mengalir dari bahagian-bahagian litar HIDUP atau dari bahagian pengalir elektrik (yang HIDUP) dengan ketiadaan kegagalan penebat.

What are their differences?

========

a. Earth fault protection is intended to protect equipment when an insulation fault occurs, for instance a direct contact between a live conductor and earth. In such a situation, great fault currents will flow back to the transformer through its neutral point when its connected to earth

b. This is not the case of earth leakage protection, where faulty currents are generally much lower and the protection is dedicated, for example, to avoid hazards to human beings or animal
