Product Description
Every electric wire in your plant-whether it's in a motor, generator, cable, switch, transformer, etc.-is carefully covered with some form of electrical insulation. Insulation is there to protect your electrical assets-resisting current and keeping the current in its path along the conductor.
The purpose of insulation around a conductor is much like that of a pipe carrying water. Pressure on water from a pump causes flow along the pipe. If the pipe were to spring a leak, you'd waste water and lose water pressure. With electricity, voltage is like the pump pressure-causing electricity to flow along the wire. Like a water pipe, there is some resistance to flow along the wire, but it's much less than it is through the insulation. The more voltage we have, the more current there will be, and the lower the resistance of the wire, the more current at the same voltage. "Good" insulation has a relatively high resistance to current. When your plant electrical system and equipment are new, electrical insulation should be in great shape. But with normal wear and tear-combined with electrical stresses like mechanical damage and vibration, plus environmental factors including heat, cold, dirt, oil, vapors, moisture, or humidity-insulation can degrade. As pin holes or cracks develop, moisture and foreign matter penetrate the insulation's surface, providing the perfect low resistance path for leakage current. Earliest tests on insulation systems involved applying a DC voltage across the insulation and measuring the leakage, or resistive current, through it. The insulation resistance test is as relevant as ever and, in many applications, is preferred to other insulation test methods. Today Weshine offers the finest line of 5 kV, 10 kV and 15 kV (DC) insulation resistance testers available anywhere. In particular, Weshine VS-3127 is a battery powered insulation tester with digital and analogue arc display, designed for high voltage insulation resistance testing in the maintenance and servicing of cables, rotating plant machinery, transformers, switchgear and industrial applications. DC insulation tests are performed at 250 V, 500 V, 1000 V, 2500 V, 5000 V, 10000 V, 15000 V. Insulation resistance measuring range is 100 kΩ to 30 TΩ. Automatic discharge for capacitive circuits under test is provided and decaying voltage displayed.
