China High Quality digital clamp Supplier – GDHX-9700 Phase Detector – HV Hipot
China High Quality digital clamp Supplier – GDHX-9700 Phase Detector – HV Hipot Detail:
General Information
GDHX-9700 Phase Detector is mainly used in electric power lines, phase, and phase sequence calibration in substation, with main functions including electrical inspection, phase calibration and phase sequence measurement. It uses double shielding and brand-new digital circuits, with strong anti-interference, accorded with EMC standards, suitable for various electromagnetic interference situations.
The high voltage phase signal of measured lead will be transmitted directly after treatment, the handset will receive and make phase comparison, determine the results after phase detection, real-time display phase angle difference and vector. It uses wireless transmission technology, safe and reliable, fast, and accurate, suitable for using at different voltage levels (10V-500KV). When checking the grid structure, it can accurately identify the relative phase of different leads for the three-phase connected line, without any electrical connection between two measurement components, which makes the application of the measurement device very flexible and safe.
Features
● Voltage range: 10V~500KV, applicable for various voltage grades.
● Accuracy: short distance: error ≤±3°; long distance: error ≤±3°.
