Sensors placement
Sensors placement
Connect SAM4 sensors to the output (secondary side) of the existing VTs and CTs, positioned as close to the motor as possible — ideally at the last accessible point before the feeder exits toward the motor, after any power factor correction banks or similar equipment. This ensures the reading reflects exactly what the motor receives from the VT/CT secondaries.
