Insulation Testers

Electricity has been used for more than a century. It has brought great technological advancements, and rapid industrialization made it a crucial part of the commercial and industrial spheres. Nowadays, electricity powers almost any device we use. Electricity brings huge benefits, but if mishandled or not treated properly, it can pose a serious threat to human life. A variety of devices were introduced to prevent damage and injuries to users. A basic protection measure that is used on all wires, cables, and electronic gadgets is insulation. It separates the internal part of a wire or electronic equipment from the surrounding environment, reduces the heat loss or gains, and, most importantly, protects the user from electrocution. A complete and undamaged covering is necessary for the safe and efficient performance of an electrical device or electric system.

Sometimes a malfunction may be caused by deficient insulation. If there are no visual defects, but the equipment or electric system doesn’t work properly, an additional gadget is required to detect the reason for bad performance. An example of such a testing device is an insulation tester. It’s a specialized gadget that is needed to measure the resistance of insulation to the electric current flowing through it. The resistance is high if the insulation does not let out any current through. If there is a constant current seeping through the covering, the resistance drops significantly. This predicted pattern allows the testing device to establish if there is a faulty covering. Moisture and temperature are inconsistent factors that may affect the measurement. Defining the result is not always presented in numeric values. If brand new wiring or equipment is tested, the results are compared to the pre-set requirements, given by users or manufacturers. If you are performing a maintenance check, the results need to be compared to previous tests to determine the pattern.
