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.
