Insulation resistance tester is suitable for all kinds of electrical equipment maintenance, repair, test and verification of insulation testing. The insulation resistance dividing line is uniform and clear, and the reading is accurate. Easy to operate and carry. Low power consumption, battery powered, long service life. Has the function of battery capacity check.
What happens when electrical insulation fails?
Electrical insulation is not just the plastic polymer material that wraps wires. It is a complete system consisting of cable insulation, casing insulators, interpipe, motors and general purpose equipment. Mechanical pressure, contamination, and temperature changes can all cause these components to deteriorate over time, leading to current leakage. Leakage of current may cause the following problems:
1, when the current through the insulation layer to generate heat, will make the insulation layer deterioration, until insulation failure, and will form a fire hazard.
2. The leakage current must be returned to the source, and it will flow back to the source through any available conductor, line pipe, pipe, water or ground. This unfavorable current creates a dangerous voltage.
3, leakage current efficiency is not high. Leakage current through the insulation layer does not drive the motor, does not emit light or heat, but still generates consumption.
4, leakage current will cause overcurrent protection device trip, so that the motor and transformer overheating. The result is poor electrical insulation, which leads to equipment failures and production line shutdowns. Now, no plant can afford unplanned shutdowns. "Customers need to diagnose faults quickly. No one wants to waste production time, and many customers are eager to know whether they need to repair or simply replace equipment."
