Insulation Resistance Tester: Its Types and Uses

What is an Insulation Resistance Tester?

An insulation resistance (IR) tester measures the resistance of any two points separated by electrical insulation. 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.

3 Methods of Testing Insulation Resistance

Below-given are the three methods used for testing insulation

resistance-

• Spot Reading test,

• Time Resistance test,

• Step Voltage test.

These three tests can let users get insulation results in motors, cables, generators, and transformer insulation.

Objective of Insulation Resistance Tester

In short, insulation resistance testers ensure the wires and motors work correctly. 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.
