Insulation testers are the ideal tool for preventative or predictive maintenance programs designed to identify potential equipment failures before they occur. They are perfect for testing a wide range of high voltage equipment including switchgear, motors, generators and cables.
Ideally all electrical current sent along a conductive wire should reach its intended destination. However you do find that some of it is lost along the way due to various reasons. Wires are insulated with a resistant sheathing to contain the conductivity of the typically copper or aluminium core, but even with this insulation in place, some of the current still manages to escape. The electricity that leaks out can be detrimental to electrical circuits and machinery. Testing can help you determine whether the insulation is performing at an effective and safe level. Excessive heat or cold, moisture, vibration, dirt, oil and corrosive vapours can all contribute to deterioration therefore routine testing can identify problems before they result in injury or equipment failure.
Testing the integrity of insulation requires measuring its resistance to current flow across it. A high level of resistance means that very little current is escaping through the insulation. Conversely, a low level of resistance indicates a significant amount of current may be leaking through and along the insulation.
What is the purpose of insulation testing?
A quality control measure at the time a piece of electrical equipment is produced. An installation requirement to help ensure specifications are met and to verify proper hook-up A periodic preventive maintenance task A troubleshooting tool
Insulation testers provide noise free, reliable results. They are safe and easy to use and the ideal solution for troubleshooting, commissioning and preventative maintenance applications.
