Insulation Resistance Tester Its Types and Uses
                     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.
