The Importance of Regular Insulation Resistance Testing in Industries

Though conductive wires are insulated with resistant sheathing made of materials such as aluminium and copper, it’s not rare for an imperfection to occur in the insulation leading to a leakage of the electric current.

When you’re working in industries, greatly depending on machinery, you simply can’t afford for this to happen considering it can be detrimental to both the machines and the circuits. Think of the example of the damage that happens when a leak is present in a motor, the current reaching parts where it shouldn’t; sounds like a mess, right?


You have to agree it sounds scary and apart from the costs that would come out of this, requiring you to repair or buy new machinery entirely, your work could be affected, the productivity specifically coming to a halt for some time which leads to more losses.

What can be done to prevent this and the huge costs resulting from it is regular insulation resistance testing to be sure the insulation is functional and safe with one of the top-notch testers, like Meggler, AEMC or any other 10kv insulation tester.

Built with operator safety and efficiency in mind these testers are created to provide various diagnose tests thanks to the different testing modes, such as IR, timed IR, DD, SV, PI, DAR, at variable voltages (e.g. 1kV to 10kV) and are useful for all kinds of applications.

Whether you need to check the electrical wiring installations and switchgears, the cables, valves, pumps or test motors, count on the help of a 10kv insulation tester. Relying on this kind of equipment and testing, you’d be able to detect minor issues on time, as well as something serious like the current dropping and act immediately before failure happens, both with the machinery and the systems.

Having in mind exposure to various elements, as is the example with extreme heat, cold, dirt, oil, moisture or even vibration can affect the insulation badly, an insulation tester can help you come to the root of the problem so you can prevent such damages in the future.

To ensure your machinery investments are taken care of, it’s advisable to carry out insulation resistance testing as soon as they’re installed and regularly check them throughout their lifespan.

Along with the importance of scheduling the tests frequently, prior to conducting them it’s necessary to disconnect any equipment connected to the equipment you’re about to check, shut down machinery and discharge the capacitance.
