High-Voltage Wireless Phase Comparator

ME-WTAG6000C High-Voltage Wireless Phase Comparator (hereinafter referred to as "the instrument") is designed for phase verification during the parallel connection of two high-voltage lines or in ring networks. The instrument is suitable for phase verification on AC transmission lines ranging from 5V to 500kV and secondary live-line indicators, while also featuring live-line detection functionality.

Employing wireless transmission technology, the instrument ensures safe and reliable operation with user-friendly functionality, overcoming numerous limitations of wired phase comparators. Additionally, the instrument supports upgradeable phase sequence detection and remote phase verification capabilities.

I. Practical Functionality and Broad Applicability

Phase verification over AC transmission lines from 5V to 500kV is made possible by extensive voltage coverage. incorporates live-line detection capabilities and simultaneously offers phase verification for secondary live-line indicators.
allows for functional updates and may be expanded with capabilities for remote phase verification and phase sequence detection to support a variety of application situations.

II. Excellent Technical Performance and Accurate Measurement

Reliable phase verification findings that meet National Standard Class A (with ±30° as the phase distinction criterion) are provided by high phase difference accuracy with error ≤5° and frequency accuracy up to ±0.1Hz.
Low leakage current (<10μA) while measuring at a high voltage. Low energy consumption and improved safety are ensured by transmitter operating power consumption of less than 0.1W and receiver host operating power consumption of less than 0.3W.

III. Easy-to-use functionality and experience

A maximum line-of-sight distance of around 100 meters between transmitter and receiver is made possible by wireless transmission technology, which removes cable limitations for flexible operation.
provides straightforward clarity by concurrently displaying phase difference, frequency, vector diagrams, and phase-matching results for both lines on a 3.2-inch color display. facilitates quick decision-making by supporting voice prompts for operational procedures and measurement outcomes.
has an automated shutdown feature to save energy after an hour of inactivity. A buzzer functions as a live-line warning and a battery status indication when the transmitter comes into contact with a high-voltage line (three beeps indicate full charge, two beeps indicate useable power, and continuous beeping indicates low power).

IV. Dependability and Safety with All-Around Protection

It is made of materials that meet IEC/1C78 requirements and has a 5-meter standard insulated rod (suited for ≤500kV voltage). Meeting several national and power industry regulations, it has impact resistance, moisture resistance, and high-voltage endurance.
explains high-voltage testing safety procedures in detail, including the handed position of the insulated rod to reduce the danger of electric shock. A 2-megohm internal resistor in self-test leads removes the risk of electric shock when people come into touch with alligator clips.
Dedicated rechargeable lithium batteries with a 5V charger are used by both transmitter and receiver devices, removing the risk of hazardous battery change.

V. Convenient Maintenance and Rational Structure

Two transmitters, one receiver unit, an insulated rod, a charger, and an accessories case are all included in the clear component division. For a variety of installation scenarios, transmitters are attached to telescopic insulated rods via mounting holes.
The only maintenance needed is a full charge for long-term storage and a monthly recharge. Steer clear of areas that are dusty, hot, or humid. To guarantee operational safety, do a withstand voltage test on the insulated pole before to first use and every year after that.

VI. Flexible in Various Grid-Connection Situations

Both generator quasi-synchronization (low impact, appropriate for big generators) and self-synchronization (fast speed, appropriate for small hydropower) grid-connection techniques are supported by phase comparison findings, satisfying a variety of power system integration requirements.
