Insulation Resistance

Rent the Megger 210415 Megohmeter for Accurate Insulation Resistance Testing

Insulation resistance testers can be used to determine the integrity of windings or cables in motors, transformers, switchgear, and electrical installations. The test method is determined by the type of equipment being tested and the reason for testing. For instance, when testing electrical cabling or switchgear (low-capacitance equipment) the time-dependent capacitive leakage and absorption leakage currents become insignificant and decrease to zero almost instantly. A steady conductive leakage current flow is reached almost instantly (a minute or less) providing perfect conditions for the spot-reading/short-time resistance test.

Megger 210415 Measures Insulation Resistances of Up to 100,000 Megohms

A megohmmeter (sometimes referred to as a megger) is an electrical test instrument designed to test extremely high resistances by producing a DC (direct current) voltage. A megohmmeter produces a high voltage, low current DC charge which allows for testing resistances commonly encountered in electric motor winding or cable insulation tests.

The Megger 210415 – a High Voltage Megohmmeter That’s Built Tough

Electrical test meters report electrical circuit properties, such as voltage, resistance, capacitance, and continuity. Available in handheld or benchtop form, they detect electrical problems in equipment, wiring, and power supplies. A variety of probes, clamps, and leads can be used to connect the meter to a circuit or device. Single-function meters, such as battery testers and voltage testers, measure one property of a circuit, and multimeters measure multiple properties. Electrical test meters display information either in analog form using a needle that moves on a calibrated scale, or in digital form on an LED screen.

Megger MIT525 and MIT1025 Insulation Resistance Testers Provide Valuable Diagnostics

Since a majority of electrical maintenance and testing involves evaluating insulation integrity, insulation resistance testing is very important. Electrical insulation starts to age as soon as it’s made, and aging deteriorates its performance. Harsh installation environments, especially temperature extremes and/or chemical contamination, cause further deterioration, and as a result, personnel safety and power reliability can suffer. Therefore, it’s important to identify this deterioration as quickly as possible so that the necessary corrective measures can be taken.
