The ETCR1800A Wireless High Voltage Detector is a high voltage detector with voltage indication, designed for voltage testing on high voltage transmission lines below 220kV, as well as testing ground voltage and induced voltage on high voltage transmission lines. The ETCR1800A consists of a receiver, detector, telescopic insulation rod, data upload software, USB communication cable, and other components. Today, we will conduct field tests with this high voltage detector.
There are two environments for the field tests: one is a 10kV overhead transmission line, and the other is a 10kV transformer primary side line, to test the performance of the instrument in different environments.
Before starting the test, it is essential to ensure safety measures are in place. The testing personnel should wear protective helmets, insulating gloves, insulating boots, and other insulating gear. First, assemble the insulating rod by adjusting the telescopic insulating rod to the required length, pulling each section of the rod to the end, and then tightening it with a twist to secure it in place. After setting up the insulating rod, proceed to mount the detector on the end of the insulating rod. Align the protrusions of the detector with those of the insulating rod and tighten the screws.
After installing the detector, turn on the device and the receiver simultaneously, and wait for the detector and receiver to communicate properly before starting the test. Normal communication is indicated as follows:
During the 10kV overhead transmission line test, the detector was raised to the high-voltage line using the insulating rod. The detector's hook was placed on the exposed cable wire. At this moment, the detector issued an alarm, the red LED light flashed, and a beeping sound was heard. The receiver displayed a line voltage of 10kV and a ground voltage of 5.6kV.
For the 10kV transformer primary side line test, the detector was raised to the transformer's high-voltage side with the insulating rod. The detector's hook was placed on the exposed cable wire of the transformer's primary side. At this moment, the detector also issued an alarm, the red LED light flashed, and a beeping sound was heard. The receiver displayed a line voltage of 10kV and a ground voltage of 5.1kV.
Test Results: The ETCR1800A Wireless High Voltage Detector effectively and quickly issued visual and auditory voltage alarms. The voltage level display was accurate, and the ground voltage measurement was precise. Besides voltage alarms, the instrument can display voltage levels and measure ground voltage. It can be used for voltage testing, detecting line voltage levels, detecting residual induced voltage in high voltage lines, and line fault patrol, effectively protecting the safety of operational personnel.
