Electrical Insulation Resistance Tester

Insulation cannot be perfect in the same way that something cannot be frictionless.

Electrical insulation resistance tester.

A megohmmeter also called insulation resistance tester teraohmmeter is used to measure the ohmic value of an insulator under a direct voltage of great stability. Take advantage of the 1507 full feature set to easily and quickly perform advanced insulation resistance testing. Fluke s digital insulation resistance testers provide reliable results whether you work on motors generators cables or switchgear. The insulation resistance test is an electrical test which uses a certain type and level of voltage 500v d c.

Insulation resistance testing applications and how they apply to your testing needs consider the equipment to be tested test voltage requirements the testing environment other possible uses the experience level of those using the tester and measurement safety features of the insulation resistance tester. Insulation can become worn damaged or break down due to moisture or age.

Megohmmeters also known as insulation testers or megger testers measure resistance to determine current leakage and identify faulty insulation. The megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator. This means that there will always be a little bit of current travelling through. The fluke 1507 is a versatile compact handheld insulation tester for advanced industrial and electrical insulation testing.

For low voltage installations i e. Its multiple test voltages make it the ideal tool for many troubleshooting commissioning and preventative maintenance applications.

The measured resistance indicates the condition of the insulation between two conductive parts. An infinite resistance would be the perfect result but no insulator is perfect so the higher the reading the better.
