Product Description

Product Description

summarize
The specific application of zero-sequence current protection can install a current transformer (CT) on each three-phase line, or let the three-phase wire pass through zero-sequence CT together, or install a zero-sequence CT on the neutral line N, and use these C.T to detect the sum of three-phase current vectors, that is, zero-sequence current Io, IA+IB+IC=Io. When the three-phase load connected to the line is completely balanced (no grounding fault, and do not consider the leakage current of the line and electrical equipment), Io=0; When the three-phase load connected to the line is unbalanced, then Io=IN, and the zero sequence current at this time is unbalanced current IN; When a ground fault occurs IN a phase, a single-phase ground fault current Id is generated. In this case, the detected zero-sequence current IO=IN+Id is the vector sum of the three-phase unbalanced current and the single-phase ground current.
