The KDHX-3208 wireless high voltage nuclear phase meter produced by our company is mainly used in phase verification and phase sequence verification of power lines and substations, and its main functions include electricity inspection, nuclear phase, phase sequence measurement, etc. This product adopts double shielding and new digital circuit, has strong anti-interference, meets the requirements of (EMC) standard, and ADAPTS to various electromagnetic field interference occasions.
 
The high-voltage phase signal of the measured wire is directly transmitted after processing, and the phase is received by the handheld computer and compared. The result after the nuclear phase is qualitatively determined, and the phase Angle difference and vector diagram are displayed in real time.
 
This product uses wireless transmission technology to achieve safety, reliability, fast and accurate, different voltage levels (10V-500KV) are applicable. When checking the structure of the power grid, the relative phase of different wires can be accurately identified for the three-phase connection line, and there is no electrical connection between the two measurement components, which makes the application of the measurement device very flexible and safe.
