Installation
Noted: Before installing the Rogowski CT on monitoring circuits, first you need to wire the Rogowski CT with paired energy meter.
Noted: The clamping up installation direction of CT must be according to the actual forward current direction. [Normally consider the direction from source to loads as forward current direction]
