High Voltage Wireless Phase Verifier
It is applied to phase verification and phase sequence verification in power lines and substations. It has functions such as phase verification, phase sequence measurement, and voltage detection, with strong anti-interference capability, meeting (EMC) standard requirements, and is suitable for various electromagnetic field interference occasions. The high-voltage phase signal to be measured is extracted by the collector and directly transmitted after processing. The phase verifier receives it and performs phase comparison, qualitatively determining the result after phase verification. Because this product uses wireless transmission, it truly achieves safety, reliability, speed, and accuracy, and is suitable for various phase verification occasions.
Technical Parameters
