What is Earth Fault? It’s Causes, Effects and Protection

Earth fault is an open circuit ground fault in which any live conductor or power-carrying cable is detached from its place or breaks and falls on the earth’s surface. In other words, We can say that ln earth-fault current-carrying conductor comes directly in contact with the earth’s surface.

Core Balance Current Transformer (CBCT) or Zero Sequence CT (ZCT)

A core balance current transformer (also termed as CBCT) is a ring-type current transformer (CT) through the center of which either three single-core cables or a single three-core cable of three-phase system passes. That three-core cable forms the primary winding of CBCT.
