HZHX-W fully intelligent wireless high and low voltage phase tester,also known as fully intelligent wireless high voltage voice phase tester,wireless high voltage phase tester,phase tester or phase instrument for short,consists of a wireless receiver,XY detectors,and a telescopic insulating rod.The receiver features a 3.5-inch true color LCD screen that simultaneously displays phase testing results,phase angle,frequency and vector diagram indicators,along with voice prompts such as"X signal normal","Y signal normal","in phase","out of phase",for clear and intuitive operation.The phase testing distance can reach up to160 meters in open ground.It iscapable of fully intelligent phase testing for voltage lines from 10Vto 550kV. For bare conductors of 35kV and below,direct contact phase testing can be performed.For bare conductors above35kV,non-contact phase testing is employed by gradually approaching the detector to the conductor.Up on sensing the electric field signal,phase testing is completed without direct contactwith high voltage conductors,enhancing safety.The phase tester also functions as a high voltage tester,high voltage phase meter,and high voltage phase sequence meter,suitable for voltage testing,phase sequence testing and transformer group determination.
1. Utilizes Wireless Transmission Technology
2. Safe and Reliable Operation
3. Easy to Use
4. Suitable for live working on AC transmission lines from 0.22KVto 220KV and live working onthe secondary side,with high voltage detection functionality
