CT installation for protection relays
Cause
The specifically designed CSH120 and CSH200 zero sequence current transformers (CTs) measure direct residual current (Ir). The only difference between them is the diameter. Due to their LOW_VOLTAGE insulation, they are used only on fully insulated cables.
