Digital phase detector TAG-8000

wireless

The TAG-8000 Wireless HV Phase Tester is a portable wireless device for identifying phase and phase sequence on high-voltage lines connected to the grid or the core conductor of ring networks. It provides qualitative (sound and light) and quantitative (real-time phase-angle difference) indications and is designed for safe, convenient field use.

Main features

• Wireless multi-mode HV phase detection for broad field applicability.
• Qualitative and quantitative indications: audible/visual signals plus real-time numeric phase-angle difference.
• Interactive user interface with configurable backlight and automatic shutdown settings.
• FCC antenna design and double shielding for improved signal strength and EMI resistance.
• Charting, numeric display and historical data browsing for easier analysis.
• Field-calibration function to maintain phase-angle accuracy.

Additional information

• Delivered as a handset (main unit) and two detectors (X and Y) for non-contact detection and wireless transmission.
• Intended to check whether two HV lines are in-phase or out-of-phase and to verify phase sequence (normal or reversed).
• Phase-sequence verification by 120° clockwise / 240° counterclockwise assessment.
