Product Details

• 
  The wireless high voltage phase verifier is used for phase calibration and phase sequence verification in power lines and substations. It has functions such as phase verification, phase sequence measurement, and voltage detection. It has strong anti-interference capability, complies with (EMC) standard requirements, and is suitable for various electromagnetic interference environments. The high-voltage phase signal to be measured is taken out by the collector, processed, and then directly transmitted. The phase verifier receives it and performs phase comparison, and then determines the result after phase verification. Because this product uses wireless transmission, it is truly safe, reliable, fast, and accurate, suitable for various phase verification occasions.

Safety Precautions

1.  During on-site testing, operators should operate in accordance with the relevant requirements of the "Safety Work Regulations for Electric Power".
