Sometimes called meggers or insulation testers, megohms are electrical meters usually used to measure the condition of insulation in motor windings and wire insulation. Regularly using a kilometer for insulation checking in both brand new installations and periodically as part of an ongoing maintenance scheme is an advisable way to make sure your motor circuits are free from any possible fire hazards. By checking the insulation, it will be easier to locate and repair any damaged areas and avoid any electrical shock that may result.
Megger Insulation Testers
Insulator testers and meters are essential tools for ensuring you do not have any leaks in the wiring of your house or building. They are also useful in inspecting any areas where insulation can be installed such as in ceilings, doors and windows. The type of insulator you use will depend on what you are doing. A more permanent insulation would be made of plywood or cement board whereas for temporary insulation such as windows and doors, an insulating material such as cotton wool may be used.
Insulator testers are generally very small and lightweight and come with a plug which means you can carry them with you if you need to check the insulation of your home. Some of these testers are easily portable and can be transported from one location to another without too much trouble. You can either go out and buy a small one or you can make one yourself by following some good advice from a friend who has done it before you and save some money by doing it yourself.
