Abstract
A procedure to measure the grounding resistances of electrical installations by measuring the loop impedance. According to this procedure, using voltage generator transformers, a current is injected into the loop and this current is measured using current measurement transformers. Two transformers are united into a single transformer, used as impedance transformer, and the loop impedance is established by taking several measurements that allow determining and eliminating parameters of the transformer, by analysis of the measurement results.
