Insulation Resistance Tester

Fluke s digital insulation resistance testers provide reliable results whether you work on motors generators cables or switchgear.

Insulation resistance tester.

The megger insulation tester is a small portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. Resistance test 50 100 125 250 500 1000 v insulation measurement up to 40gω. The megger insulation tester is essentially a high range resistance meter ohmmeter with a built in direct current generator. 1 insulation resistance ir this is the simplest of the tests.

When using an insulation resistance tester to measure insulation resistance japanese standards require certain voltage values to be applied by the instrument for certain measurement targets as shown in the table on the right it is necessary to select from the multiple application voltage values rated measurement. Rated standard measurement voltage and example uses. What is insulation resistance testing. Only the current through the insulation is measured since any surface current will be returned on the guard lead.

Output voltage can be optionally set in the range of 25 to 1000 vdc with a resolution of 1 v. Klein tools et600 megohmmeter insulation resistance tester multimeter 4000 megohm resistance 125v 250v 500v 1000v test voltage. Portable insulation resistance testers and megohmmeters are designed to help prevent hazards such as electric shock and short circuits caused when the insulation in electrical devices parts and equipment used in industrial plants buildings and other settings degrades over long periods of use. Basically there are three different tests that can be done using a megohmmeter.

World s fastest measurement speed 0 5 sec six ranges available for insulation. Digital insulation resistance tester for photovoltaic generation systems. The insulation resistance test is an electrical test which uses a certain type and level of voltage 500v d c. Resistance test 50 100 125 250 500 1000 v insulation measurement up to 40gω.

For low voltage installations i e. The measured resistance indicates the condition of the insulation between two conductive parts. Diagnostic insulation test. 4 6 out of 5 stars 69.

Built in pv dedicated function 600 v ac 1000 v dc meter 5 test voltage ranges from 50 to 1000 v. 230v to measure insulation resistance in ohm s. Safely and accurately measure even while pv system is generating solar power.
