Merytronic PI-3

De-energized 3-Phase Identifier

Merytronic PI-3 de-energized phase identifier is a robust, user friendly and advanced digital tool. It helps users to easily identify any de-energized electric cable and its phases, among multiple conductors, in substations, trenches, manholes, panels, aerial/underground conversions, etc.

The transmitter includes three inductive clamps and three crocodiles. Therefore, it can detect each one of the phases of a feeder without changing the transmitter connection. It also helps to identify both de-energized cables prior to be cut and open cables (once they have already been cut) to join the phases of both sides correctly.

Use cases:

• Phase identification in cables with both ends in short-circuit
• Identification of phases in cut cables without short-circuit
• Join two three-phase lines phase to phase

With a single device, any types of cables can be identified in both Medium and Low Voltage and it does not require calibration prior to identification
