GDJY Insulating Resistance Tester I. General introduction Electric test rules conduct a series of insulation performance test on the requirement of various electric equipment such as cable, electric engine, electric generator, transformer, mutual inductor, high voltage switch and lightning arrester etc, first it shall conduct insulation resistance test. In recent years with the quick development of the electric industry, the usage of large capacity equipment increases continuously, the common megohmmeter cannot test its insulation performance. When testing the insulation resistance of large capacity electric equipment, the insulation resistance value is related to the charging time, the longer the charging time is, the higher the insulation resistance value is, this phenomenon is called the absorption phenomenon of insulation. To know the insulation performance of the tested product, it shall first do the absorption factor and polarization index test on it, and provide safety guarantee for the insulation performance tests of the next stage such as leakage, media wastage and partial discharge. The company promotes according to the electric standardization rules the GDJY intelligent insulation resistance tester (hereinafter referred as GDJY) to conduct the insulation, absorption factor and polarization index test on the electric equipment, provide preliminary accurate judgment on the series insulation test. Since the charging time directly affects the insulation value test of large capacity condensive test piece, so it needs the large charging current, the stronger the charging capacity is, the closer the absorption factor test value to the real value. GDJY short circuit current is larger than 3.5mA, it overcomes the malpractices such as small short circuit current, inaccurate test and liable to be interfered of common megohmmeter. The GDJY adopts the real time voltage current sampling to do the dividing computation, so in the testing, even if the voltage changes, the resistance value obtained from the ohm theorem is still accurate. The megohmmeter adopts advanced single chip control process and human machine interface dialog, it is easy to bring, simple operation, the accumulator is attached inside and it is AC/DC two purposes, it has under voltage protection and cell overcharge protection. The device can automatically display the current time, save 8 groups of historical test data and time, it offers great convenience for the test personnel. GDJY is a new type intelligent device and is your best choice. II. Main technical index 1. Output voltage: DC500V ,DC1000V ,DC2500V, DC5000V Error:
