is an advanced device specially designed for the power industry, used for safe and accurate phase comparison in high-voltage environments. This type of instrument is crucial in power system applications, especially during grid interconnection, loop network operations, line maintenance, and fault troubleshooting, ensuring phase consistency between different lines and preventing power accidents caused by phase mismatch.
Technical Parameters and Features
Accuracy: Same-phase error ≤15°, different-phase error ≤15°, ensuring precise phase verification.
Sampling Rate: 3 times/second, capable of rapid response to capture instantaneous phase changes.
Power Supply Voltage: The power supply voltage for X and Y collectors is 7.5V±1.5V, with low power consumption design, operating current ≤5mA, ensuring long-term stable operation.
Wireless Transmission: Utilizes wireless technology, eliminating the limitations of wired connections, enhancing operational flexibility and safety.
Working Principle: Composed of a transmitter and a receiving host. The transmitter measures the phase and frequency of the line and sends the data to the receiving host via radio, which calculates the phase difference and determines the phase relationship.
Operational Convenience: Requires only one operator and one supervisor, simplifying on-site workflow.
Applicable Scope: Suitable for live-line work on 220V to 220kV AC transmission lines, covering a wide range of voltage levels.
Safety: Overcomes the limitations of wired phase verifiers, avoiding the danger of direct contact with high-voltage lines, enhancing operational safety.
Usage Methods and Precautions
Preparation: Vertically mount the meter head on a tripod, ensure correct wiring, connect wires by color to the test rod and instrument, and properly ground the grounding wire.
Phase Verification Operation: Touch the test rods to the corresponding lines respectively, and judge whether the two lines are in phase based on the instrument indication. If the indication is close to or equal to zero, the two phases are in phase; if the indication is large, further verification is required.
Voltage Detection Function: Touch one test rod to the line and the other to ground or another phase line. A large indication indicates the line is live, otherwise it is dead.
Daily Maintenance: After use, store properly, avoid moisture and impact, regularly perform functional checks and calibrations to ensure the instrument is in good condition.
Summary
The introduction of the 35KV High Voltage Wireless Phase Verifier has greatly enhanced the safety and efficiency of power operations, making it an indispensable tool for modern power system maintenance. Its wireless design, high-precision measurement capability, and simple operation process enable easy completion of phase verification tasks even in complex working environments, ensuring the normal operation of the power system.
