Electrical connector is an important part of industrial products, in order to ensure the performance of industrial products, manufacturing will be its insulation resistance test. The simplest insulation resistance test method is fast measurement or point-reading measurements. Apply a test voltage of 30 seconds or 60 seconds to the measured object while reading the resistance value. Since the insulation resistance measured by this test method is susceptible to temperature and humidity, the measurement must be made at the normalized reference temperature. The results obtained after the test and the previous measured current value of the comparison, analysis of the current insulation quality. Through this test method can be more clearly the equipment and equipment insulation performance changes are shown, more representative. Fast measurement is susceptible to temperature and humidity. To ensure stable and reliable performance of the electrical connector, a continuous measurement method can be used to continuously measure the insulation resistance over a specified period of time. This method is not affected by temperature, Measuring equipment in the measurement process, the temperature does not produce drastic changes. In order to ensure a clear assessment of insulation monitoring, and to test any changes in the periodic measurement, the test voltage, test time to be consistent.

With the change of time, the absolute value of the electrical connector resistance may drop, the resistance drop is more likely to be concerned with a relatively low resistance but relatively stable case. If the resistance decreases, it is still higher than the recommended minimum resistance Value, then it is certainly a problem that needs to be investigated, by observing its resistance to the absolute value of the rise and fall can determine whether its performance is stable. It is also a relatively desirable method to test the insulation resistance by routine monitoring of preventive maintenance of rotating machinery. More reasonable detection method or in the regular maintenance plan using insulation resistance tester on a regular basis for insulation resistance test and record.

Regardless of the method used to test the insulation resistance of the electrical connector, the insulation material must be in good condition, and if the insulating material used is in good condition, the leakage current will be very low and the initial test will be caused by the charge current and the dielectric current , And the test voltage continues to increase, with the interference current decreases, the insulation resistance measurement will rise; if the insulation material is not good, there is damage, dirty, wet and other conditions, it will produce a high leakage Current, more than the capacitor charge current and dielectric absorption current, insulation resistance test will soon become stable.
