Working Principle
The working principle of the wireless high-voltage phase verifier is based on the phenomenon of electromagnetic interference. It consists of a transmitting unit and multiple receiving units. The transmitting unit generates a wireless signal of a specific frequency and sends it to the point under test. After the receiving unit receives the signal, it determines the phase relationship between current and voltage by comparing the phase difference between the received signal and the transmitted signal.
Main Functions
Phase Verification: Verify the phase consistency between two or more power sources.
Phase Sequence Measurement: Determine the order of phases in a power system.
Voltage Detection: Check whether the line is energized.
Technical Features
Wireless Transmission: No physical connection is required, reducing installation and maintenance complexity and improving safety.
Voice Prompts: Some models are equipped with voice functions, such as "same phase" and "different phase", for convenient operation in noisy environments.
Remote Operation: Supports signal transmission over long distances, typically up to 100 meters or more.
Multi-function Integration: In addition to phase verification, it can also perform frequency measurement, phase sequence detection, etc.

Purchasing Suggestions
When choosing a wireless high-voltage phase verifier, consider the following points:
Voltage Range: Ensure the instrument's voltage range covers your application needs.
Complete Functions: In addition to the basic phase verification function, do you need additional functions such as voltage detection and phase sequence detection?
Transmission Distance: Choose an appropriate transmission distance based on the actual needs of the work site.
Durability: Check the manufacturing quality and warranty policy of the equipment.
User-friendliness: Including the clarity of the operation interface, whether there are voice prompts, etc.
