※Selection instructions
Suitable for three-phase three-wire system and three-phase four-wire system
The compensation current can be determined through actual measurement data, or the compensation current can be calculated through detailed information of the power system (transformer, load conditions, etc.)
Three-phase four-wire system requires 3 CTs (for A-phase, B-phase and C-phase)
Three-phase three-wire system requires 2 CTs (for A phase and C phase)
