When installing new electrical machinery or equipment, testing insulation resistance is important for two reasons. First, it ensures that the insulation is in adequate condition to begin operation. This type of initial test is usually referred to as a proof test. Second, it provides a baseline reading to use as a reference for future testing.
Much like a leak in a water pipe, an imperfection in the insulation of a wire allows a steady flow of electricity to escape, which can be detrimental to electrical circuits and machinery. However, testing can help you determine whether the insulation is performing at an effective and safe level. Our selection of insulation testers can be used for routine testing to identify problems before they result in injury or equipment failure.
