Product Description

HVHIPOT GDHX-9700 Remote Wireless HV Phase Detector 
 

General Information

GDHX-9700 Phase Detector produced by HVHIPOT is mainly used in the three-phase phase detection from in power system and in switchgears. At the same time, it is also applicable to phase detection and phase sequence detection of power lines and substations, including high voltage detection. This product USES double shielding and brand-new digital circuit, has the extremely strong anti-interference, completely conforms to (EMC) standard request, ADAPTS to various electromagnetic field interference conditions.
This product adopts GPS synchronous measurement technology and wireless transmission technology, with reliable high voltage security isolation, simple operation, stable performance. It is widely used for phase detection and phase sequence detection of high voltage equipments such as high voltage power lines, substations and power plants. In the power system, phase detection is often needed before grid-connection closes and the new substation is put into operation.
After high voltage phase signals of test wire are processed, they can be directly transmitted and received by the hand-held unit. After comparison of results, phase angle difference and vector map are displayed in real time. The phase angle difference can be measured at a very long distance. The unit can continue to work for 30 minutes without satellite-clock. It is safe, reliable, fast and accurate. It is applicable to different voltage levels (10V~500kV). When checking the structure of the power grid, the relative phase of different wires can be accurately identified for the three phase connection lines, and there is no electrical connection between the two measuring components, which makes the application of the measuring device very flexible and safe.
