GDCR1800A Wireless High Voltage Detector
GDCR1800 series wireless high voltage tester (with voltage and current indication) is specially designed and manufactured for high voltage transmission line inspection, high voltage transmission line to ground voltage, induced voltage test and current test. This instrument can test the high-voltage to ground at the same time as the alarm of the power check.
GDCR1800 series wireless high voltage electroscopes have a voltage level of 0.1kV ~ 220kV, which completely covers the power and ground voltage test of each voltage level (3kV, 6.3kV, 10kV, 35kV, 66kV, 110kV, 220kV). which is safe, reliable and saves time. It is an indispensable tool for power transmission line maintenance. During the inspection and maintenance of the transmission line, even if the line has been disconnected, due to the?capacitive effect, there may still be very high voltage through induction, which seriously threatens the safety of the operator and the operating process. Make sure the voltage has dropped to a safe and operational voltage level.
