Installation<\/strong><\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Noted<\/strong>:<\/strong> Before installing the Rogowski CT on monitoring circuits, first you need to wire the Rogowski CT with paired energy meter.<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Noted:<\/strong> The clamping up installation direction of CT must be according to the actual forward current direction.
