Hi there all
I'm looking to measure current in 3 phase cables, and would like some advice on any current clamp models you'd like to recommend. However, I'm not entirely certain on the method as well; I've used current clamps before on single phase cables, and I'm aware that you need to clamp only around the live, as the fields of the currents flowing in the live & neutral cancel each other out. Is the same true for all instruments? For three phase do you have to clamp around each live individually, or is there a method just to clamp around the 5-core cable?
I only ask in hope as in the situations where I need to measure these currents it's tricky if not impossible to clamp individually to each live core
Thanks for reading
