A phase sequence indicator for up to 700V AC is a critical safety and maintenance tool used to determine the correct phase rotation (order) in three-phase electrical systems, ensuring proper installation and operation of motors and other three-phase equipment. 

The Metravi PSI-HV set is especially designed for high voltage line and switchgear (middle cabinet, ring network, cabinet, etc) nuclear phase. The instrument especially is useful for solving the traditional nuclear phase device voltage grade limit problem.

With fully-realised, automatic Phase Detection from 10V to 500kV, you do not need to purchase multiple phase detectors based on voltage grade.

The detector not only detects Phase Sequence, but also incorporates functions for testing Phase, Frequency, Phase Frequency and so on, along with Electricity Testing & Line Circuit Voltage display.

The 3.5 inch colour LCD screen displays Phase, Frequency, Phase Sequence and Phase Detecting readings all on the same screen, simultaneously. There is also a clear, dynamic vector diagram available. When line voltage exceeds 110kV, the non-contact method is to be used for phase detection.

Voice prompts, monitoring software with online real-time monitoring, historical data reading, viewing, saving, printing and query, vector graph indication and phase indication – all these functions make it an ideal instrument.
