High Voltage Phase Detector/Audio Wireless Phase Detector (GDHX-9500)

High Voltage Phase Detector/Audio Wireless Phase Detector (GDHX-9500)Product Description

1.1 General Purpose

The "Wireless Phase Detector" is mainlyusedinelectric powerlines,substation phase andphase sequence calibration, withmainfunctionsincludingelectrical inspection,phasecalibration and phase sequencemeasurement and so on. Thisproductadoptsdoubleshieldingandentirely newdigitalcircuits,withstrong anti-interference,infullaccordance with(EMC)standards,adaptedtovarious electromagneticinterferencesituations.

The high voltage phase signal of measured lead will be launched out directly after treatment, the handset will receive and make phase comparison, determine the results after the phase calibration, real-time display phase angle difference and vector.

This product uses wireless transmission technology, thereby achieving safe and reliable, fast and accurate, different voltage levels (10V-500KV) are all applicable. When checking the grid structure, enable to accurately identify the relative phase of the different leads for the three-phase connected line, without any electrical connection between two measurement components, it makes the application of the measurement device is very flexible and safe.

1.2 Security Matters

Adopts wireless transmission technology, its basic working principle is real-time phase comparison.Please observe and follow the regulation to use of this product, in order to ensure the safe operation of the instrument, and note the ends of X and Y detector are not allowed to take withstand voltage test.The metal head parts of the insulating rodis strictly prohibitedto contact withany objects during the test.Please comply with the country's power industry safety regulations of preventive test for safety tools and products.Please pay attention to the training and examination for staffs who work on high-voltage live lines or near the high-voltage lines.Phase calibration on live equipment must be carried out by insulating rod.

Note: The safe usage length and test standards of insulating rod for "Wireless Phase Detector".(Excerpting from "Electrical safety working regulations of State Grid Corporation".)1.Safety distance between staff and the charged body during live operation.
