Wireless High Voltage Phase Detector 5V–500kV Phase Sequence Tester Manufacturer

The TAG-8600C Wireless High Voltage Phase Detector is designed for phase verification in grid connection and ring network operations of high-voltage transmission lines.

It supports phase comparison of AC transmission lines ranging from 5V to 500kV and can also be used for live line detection and phase sequence verification in power systems.

With advanced wireless communication technology, the device eliminates the limitations of traditional wired phase detectors, providing safer, more stable, and more convenient field operation.

The system consists of two transmitters and one receiving host:

• The transmitters detect line voltage status, phase, and frequency

• Data is transmitted wirelessly to the receiving host

• The host calculates phase difference between X and Y lines

• The system determines in-phase or out-of-phase condition

X line is used as reference, and Y phase is calculated relative to X.

• Suitable for 5V–500kV AC transmission line testing

• Wireless communication between transmitters and receiver

• Supports phase verification, phase sequence detection, and live line detection

• Voice prompts for operation and result guidance

• 3.2-inch color screen with vector diagram display

• Automatic in-phase / out-of-phase judgment system

• High-voltage isolation design for safety operation

• Built-in rechargeable lithium battery system

• Auto power-off after 1 hour inactivity

• Lightweight portable design for field testing

• High voltage transmission line phase verification

• Grid connection and ring network operation

• Substation phase sequence testing

• Power system commissioning and maintenance

• Generator synchronization preparation

• Live line safety inspection

• Phase difference ≥ ±30° → Out-of-phase

• Phase difference < ±30° → In-phase

Voice prompts, screen display, and indicator lights provide real-time confirmation.

If the frequency of the two lines is inconsistent, synchronization adjustment must be completed before grid connection. Power transmission is only allowed when both phase and frequency match the main grid.
