An Overview Of Grounding System (Ungrounded)
Effective grounding: Effective grounding is also called solid grounding that is without resistance or reactance. In this case co-efficient of earthing ismore than 80% Non effective grounding: When neutral to earth connection is made through resistance or reactance than the system is said to be non-effectively grounded.
