Our company specially launched the insulation resistance tester to carry out insulation, absorption ratio and polarization index withstand voltage leakage tests on the electric power equipment, providing early accurate judgment for a series of insulation tests.
Since the charging current directly affects the insulation value test of the large-capacity capacitive test product, so a large charging current is required. The stronger the charging capacity, the closer the test value of absorption ratio is to the real value.The short circuit current of the resistance tester is greater than 5mA, which overcomes the disadvantages of the ordinary megohm meter, such as small short circuit current, inaccurate test and easy interference.It adopts timely voltage and current sampling for division operation, so the resistance value calculated by ohm's theorem is accurate even if the voltage changes during the test.The tester adopts advanced single chip microcomputer control process, man-machine interface dialogue, easy to carry, easy to operate;It is equipped with high performance large capacity rechargeable battery, AC/DC, and under voltage protection and battery overcharge protection.This instrument can automatically display the current time, save the historical test data and time, providing great convenience for the test personnel.
