GSY-II-10kV Elektroskop

It is mentioned in both the international standard IEC61243-1<Live working voltage detectors Part 1:Capacitive type to be used for voltages exceeding 1 kV a.c.> and the electric power industry standard DL740-2000 <Condensing voltage detector> that All the built-in and attached self-checking unit shall be used to check all the circuits of the indicator, including the power supply and the indication function. In case the self-checking unit fails to check all the circuits, it shall be clearly notified in the instruction manual and ensure that all the circuits excluded in the self-checking are reliable. GSY series of all-loop self-inspection high voltage electroscopes is the proprietary products developed by Qifeng, with independent intellectual property. Its adoption of AC self-inspection signal to troubleshooting in the capacitance-type electroscope has filled the technology blank in the domestic capacitance-type electroscope indicator all-loop self-inspection, and created a new trail for AC high voltage electroscope all-loop self-inspection. In 2004, the products passed inspection of authoritative inspection and won the national patent. The products have also passed type test of China Power Safety Tool Quality Supervision & Inspection and Testing Center. In May 2005, the products successfully held the product accreditation convention in Shanghai Science Hall, receiving affirmation of the industrial authoritative and experts, who unanimously deemed that: GSY-II series of all-loop self-inspection AC high voltage sound-light display has reached the state-of-the-art level.
