Digital phase meter TAG-9000

multifunction

The TAG-9000 is a remote wireless high-voltage (HV) phase tester designed to verify phase alignment, check phase-sequence color marking and perform close-range grid or ring-network phase detection on live lines. It supports 5 V–220 kV AC transmission lines, secondary live-display phase detection and line live detection.

Product features

• Wireless transmission combined with GPS timing for safe, reliable and easy operation.
• Real-person voice prompts for measurement results and operation steps.
• 3.2-inch color screen displays phase difference, frequency, vector diagram and same/different phase results for two lines simultaneously, plus GPS satellite count, GPS timing status and time.
• Automatic shutdown after 1 hour of inactivity to conserve battery.
• Both transmitter and receiver use rechargeable lithium batteries; supplied with a 5 V charger. Host battery: 18650, 2500 mAh; transmitter battery: 14430, 450 mAh.
• Supports remote phasing: distance between units from 0.3 km to 800 km; local transmitter–receiver line-of-sight ~100 m.

Safety precautions

• On-site testing must follow high-voltage safety-distance standards established by the power authority.
• Standard configuration includes a 3 m insulated pole suitable for voltages ≤ 220 kV; for lines above 220 kV use longer insulated poles according to local regulations.
• When operating with an insulating rod, do not hold the device beyond the insulating-rod handle position.

Maintenance and upkeep

• Fully charge the instrument before long-term storage.
• Do not store the product in damp, high-temperature or dusty environments.
• The insulation rod must undergo a withstand-voltage test before first use and an annual withstand-voltage test thereafter.
