What is an insulation resistance tester?
An insulation resistance (IR) tester measures the resistance of any two points separated by electrical insulation. The test, therefore, determines how functional the dielectric (insulation) is in resisting the flow of electrical current. Ideally, portable insulation resistance testers and megohmmeters are specially designed in helping to prevent hazards such as electric shock and short-circuit that occur when the insulation in electrical devices and equipment used in industrial plants, buildings, and other things degrades after using them for long periods. A damaged or failed insulation can create a circuit breaker to fall or fuse to blow, resulting in a severe electrical shock to the people coming in touch with an insulated wire or a metal part touching it that is poorly configurated.
In short, insulation resistance testers ensure the wires and motors work correctly. They are quite a comfortable way to check the state of the insulation on things like wires, generators, and motor windings. This is performed by measuring the high resistance values by transmitting a high voltage signal into the tested object, which is generally a wire only. Though, it’s better to choose a reliable wire for your needs, insulation resistance testers and megohmmeters provide you with much more than that in making sure that your electrical system is in proper working order. Below-given are the three methods used for testing insulation resistance-
- Spot Reading test,
- the Time Resistance test,
- the Step Voltage test.
These three tests can let users get insulation results in motors, cables, generators, and transformer insulation.
