TAG-9000 Wireless HV Phase Comparator: GPS-Powered Grid Sync

The TAG-9000 Long-Range Wireless High-Voltage Phase Comparator is an advanced diagnostic tool designed to address critical challenges in power grid synchronization and maintenance. By integrating GPS timing technology, wireless communication, and multi-functional measurement capabilities, this instrument enables safe and efficient phase comparison, voltage verification, and grid frequency analysis across diverse operational scenarios, from switchgear cabinets to ultra-high-voltage transmission lines up to 500 kV.

1. Technical Innovation and Core Features

1.1 GPS Timing Synchronization

The TAG-9000 employs GPS satellite precision timing to achieve globally unified clock synchronization, eliminating geographical limitations for remote phase comparison. This innovation resolves the traditional constraint of 300-meter operational range, allowing simultaneous phase difference measurements between any two geographically separated power lines with an accuracy of ≤6° in timing mode.

1.2 Multi-Scenario Adaptability

Remote/Proximity Phase Comparison: Supports three modes:

Close-range mode: ≤3° accuracy (within 100m line-of-sight).

Long-range accurate mode: ≤3° accuracy (GPS-assisted).

Long-range timing mode: ≤6° accuracy (ideal for cross-regional grids).

Switchgear Applications: Enables non-contact phase verification via cabinet-mounted voltage indicators.

Multi-Voltage Compatibility: Operates across 5 kV to 500 kV systems without hardware adjustments.

1.3 Enhanced Safety and Efficiency

High-Voltage Detection: Validates live circuits with leakage current <10 μA.

Phase Sequence Verification: Identifies ABC/RST phase order for grid stability.

Frequency Measurement: ±0.1 Hz precision for real-time grid health monitoring.

2. Engineering Design and Performance

2.1 Compact and Robust Architecture

Portability: Handheld design (5 kg/unit) with 71×26×11 cm packaging dimensions.

Extended Autonomy:

2200 mAh host battery + 350 mAh transmitter battery.

30-minute backup operation during GPS signal loss.

Environmental Resilience: Operational in -35°C to +45°C with ≤95% RH humidity tolerance.

2.2 Data Management

800-Group Storage: Phase/frequency records with selective deletion capability.

A-Level Phase Judgment:

In-phase: Phase difference <30°.

Out-of-phase: Phase difference ≥30°.

2.3 Safety Compliance

Insulation: 3-meter insulated poles (220 kV rating).

Low-Power Operation: <0.1 W (transmitter) and <0.3 W (host) power consumption.

3. Field Applications and Industry Impact

3.1 Grid Maintenance Optimization

Enables rapid fault localization during grid interconnection.

Reduces outage risks through pre-emptive phase sequence validation.

3.2 Cost-Effective Deployment
