Question:

To measure current, how many transformers are used in 0-100A? How big is the ammeter? How do I get the S1'S2 line?

To measure current, how many transformers are used in 0-100A? How big is the ammeter? How do I get the S1'S2 line?

Answer:

Transformer 100/5 can wear from L1 to L2 in S1S2, the current meter, S2 connected current meter after grounding. Note! This is not salty. Current mutual open short circuit without. If open may breakdown or transformer, and the main loop arc
Under normal circumstances, if one hundred is the maximum power output of current equipment when the transformer is one hundred, 100/5 transformer can; if the rated current of one hundred a, choose 150/5, ammeter and transformer ratio should be one to.Mutual inductor S1 terminal current meter A1, A2, then S2 and then ground
If only 4 hours or more, that is, if temporary monitoring, with a caliper table monitoring can be.
