KG3200 Transmission Line Insulation Resistance Apparatus Cable Insulation Surface Resistivity Tester
Product Introduction
Power test procedures for many power equipment such as: cables, motors, generators, transformers, transformers, high-voltage switches, arresters and other requirements to do a series of insulation performance tests, the first is to do insulation resistance test. In recent years, with the rapid development of electric power industry, the use of large capacity equipment is increasing, and the insulation performance can not be detected by ordinary megohm meter.
When testing the insulation resistance of large-capacity power equipment, the insulation resistance value is related to the time of pressure, the longer the pressure time, the higher the insulation resistance value, which is called the insulation absorption phenomenon. To understand the insulation performance of the tested product, it is necessary to first do the absorption ratio and polarization index test for the next step of leakage, dielectric loss, partial discharge, etc., insulation performance test to provide security. Our company launched KG3200 insulation resistance absorption ratio tester in accordance with the electric power standardization regulations, to carry out insulation, absorption ratio, polarization index voltage leakage test for power equipment, to provide early accurate judgment for a series of insulation tests.
Because the charging current directly affects the insulation value test of the large-capacity capacitive test, a large charging current is required, and the stronger the charging capacity, the closer the absorption ratio test value is to the true value. XXX short circuit current is greater than 5mA, overcoming the common megohm meter short circuit current is small, the test is inaccurate, susceptible to interference and other drawbacks. XXX
Taking timely voltage and current sampling to do division operation, so even if the voltage changes during the test, the resistance value calculated by Ohm's theorem is accurate. The table adopts advanced single-chip microcomputer control process, man-machine interface dialogue, easy to carry, simple operation; It is equipped with high performance and large capacity rechargeable battery, both AC and DC, and has undervoltage protection and battery overcharge protection. The instrument can automatically display the current time, save the historical test data and time, which provides great convenience for the test personnel.
