Kính thiên văn quang học bằng sợi thủy tinh tự kiểm tra kép điện áp cao is a high voltage detect tool, which is composed of signal device and insulated rod. A mask integrated circuit is used inside the signal device.
During voltage detecting, the voltage signal enters the integrated circuit in the signal device, and the integrated circuit processes the voltage signal into electrical signals, and then starts voice circuit and light indication.
500kV Voltage detector is contact electroscope, automatic detection whether electrified body is electriferous or not. When the measured voltage is higher than the trigger voltage of electroscope, signal device will start the voice circuit and send out the language. At the same time, there is a light indication at the bottom of the signal device.
