A perfect solution for insulation testing troubleshooting commissioning and preventative maintenance applications. It can be useful to visualize the insulation tester as essentially a higher range resistance meter that contains a direct current generator. The insulation resistance test consists in measuring the insulation resistance of a device under test while phase and neutral are short circuited together. An insulation tester is a portable device that will provide you direct readouts of insulation resistance in ohms and megohms.

Consider the equipment to be tested test voltage requirements the testing environment other possible uses the experience level. Insulation resistance is temperature sensitive. What affects insulation resistance readings. The insulation resistance test is the second test required by the electrical safety testing standards.

A common rule of thumb is insulation resistance changes by a factor of two for each 10 degrc change. How to test insulation resistance. This is one factor that generates the continued popularity of analog testers. The measured resistance has to be higher than the indicated limit from the.

Since 80 of electrical maintenance and testing. Examine six areas when deciding on the best insulation resistance tester for the application. Some insulation resistance testers can be very large and not portable so there is a need for circuits and equipment to be verified as electrically de energized first before an insulation resistance tester is connected to the equipment so it wouldn t be a hassle for you to carry the insulation resistance tester to various locations. With advanced performance the insulation tester line is designed to be safe simple to use and gimmick free.
