Technical Features for GSY-III-110kV: 1) sine wave 2) power frequency 50Hz 3) autogenous AC 4) all-loop self-inspection 5) faulty monitor 6)monitor Ust 7)under voltage instruction 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. Based on the full-loop electroscope, Qifeng successfully developed GSY-III Power Frequency Sine Wave Full-loop Self-checking Electroscope in 2005 which passed the test of Electrical Power Industry Electrical Safety Tool and Instrument Quality Supervision and Inspection Center and granted the national patent certificate in 2006. It is pointed out in the technological investigation report issued by authority department in 2006 that in conclusion, the 50Hz power frequency sine wave signal generated by the product can fully simulate the power line and check the electronic loop of the electroscopeaccording to the analysis made by the experts, the technology involved in this project takes the lead in the industry in China and even reach the advanced level in the whole world.In 2007, this product received the Certificate of the Products in Accordance with International Standard issued by National Standardization Management Committee. Qifeng is the first company that received this certificate in the electric power safety tools and instruments industry in the mainland of China. customized as per special specification.
