Indicators of the alternation of the phases

The indicators of the alternation of phases - instruments are intended for determining the sequence of alternating the phases. The compact, safe instruments, which make it possible to determine the sequence of alternating the phases, completely insulated wire, three wires with the clamps of the type “crocodile” are fastened down three wires of three-phase network. For the greater safety of operator, the instrument can work with insulated wire, which prevent contact with the metal.
