Product Introduction
The TAG-8500 De-Energized Cable Phase Identification Tester is designed to identify and verify A, B, and C phase conductors of de-energized cables before commissioning or grid connection.
The system uses a transmitter to inject different pulse signals into the three-phase conductors and a receiver to identify the corresponding phase at the remote cable end. It is suitable for new cable installation, long-distance cable lines, switchgear, and pre-commissioning inspections.
For de-energized cables only.
Applications
- New cable installation and commissioning
- Long-distance cable phase identification
- Pre-grid-connection phase verification
- HV/LV switchgear commissioning
- Multi-terminal cable systems
- Standard live-display indicator phase identification

Key Features
- Remote Phase Identification — Identify A, B, and C phases at the remote cable end.
- Polarized Pulse Signal — Directional signals help distinguish the corresponding phase.
- Loop Resistance Monitoring — Monitor the cable circuit condition during testing.
- Clear Phase Indication — A, B, and C phases are displayed in different colors with audible alerts.
- Adjustable Signal Gain — Three gain levels help adapt to different signal strengths.
- Live-Display Indicator Testing — Supports phase identification through standard live-display indicators with the dedicated test lead.
Product Advantages
Verify Before Energization
Confirm cable phase identity before energization and reduce the risk of incorrect phase connections during commissioning.
Identify Remote Cable Phases
The transmitter and receiver work together to identify phase correspondence between different cable ends, making TAG-8500 suitable for long-distance cable projects.
Support Grid Connection
Verify that newly installed cable phases match the required phase designation before connecting the circuit to the existing power network.
Check Cable Circuit Condition
The transmitter displays the loop resistance of each phase, helping engineers identify potential open circuits, poor grounding, or connection problems.
Portable for Field Testing
The compact transmitter, receiver, and flexible receiving coil make TAG-8500 suitable for on-site cable phase identification.

FAQ
Can TAG-8500 be used on energized cables?
No. TAG-8500 is designed for de-energized cables only. Always confirm that the cable is completely de-energized before testing.
Can TAG-8500 identify phases at the remote cable end?
Yes. The transmitter sends phase-specific pulse signals through the cable, and the receiver identifies the corresponding A, B, or C phase at the remote end.
Why is loop resistance monitored during testing?
Loop resistance helps indicate the condition of the test circuit. An abnormally high resistance may be caused by poor grounding, an open circuit, or a poor connection.
Can TAG-8500 be used for long-distance cables?
Yes. The transmitter and receiver are designed to identify phase correspondence between different cable ends, making the system suitable for long cable lines.
