Safeguarding with the Ideal Industries 61-797 digital insulation meter
By Alyssa Dalton
Apr. 22, 2015 – The Ideal Industries 61-797 digital insulation meter is a rugged, industrial-grade tester designed for commissioning, routine troubleshooting and preventive maintenance to identify whether insulation is performing at an effective, safe level. Using the 61-797, the technician can determine the integrity of insulation in new and existing wiring by identifying capacitive, absorption and leakage current at multiple test voltages (50V, 100V, 250V, 500V and 1000V) and resistance up to 20G ohms. Periodic testing of insulation for signs of deterioration will spot breakdowns in electrical systems, generators, switchgear and motor windings before failure occurs, says the company, adding that insulation testing can prevent the dangerous occurrence of short circuits or short to grounds. The meter offers twist-on alligator clips that fit over the test leads. There is also a remote test button for two-handed operation.
