the insulation condition from values that are only relative. The Megger insulation tester is a small, portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. For good insulation, the resistance usually reads in the megohm range. The Megger insulation tester is essentially a high-range resistance meter. · The Megger technical library provides access to a range of additional content and resources such as technical guides, application notes and more.

Insulation Resistance Testing Purpose: Insulation resistance testing is a non-destructive test procedure. The test measures the insu-lation resistance between the phases and/or between phase and ground. It is commonly used in the industry for acceptance testing prior to energizing the cable and for maintenance testing programs. Test lead set, 6 ft ( m) (1 pr]) Carrying case; Test record cards, universal; Instruction manual; Applications: Major Megger testers measure the insulation resistance of wires, power cables, motors, generators, transformers, switchboards and electrical controls. Both models offer multiple test voltages for performing spot and step-voltage tests. Megger Quality is crafted into every Major MEGGER® Insulation Tester, with excellent test voltage regulation, direct measurement readout and an external guard terminal to eliminate surface leakage current from the measurement. Five models are available for general purpose testing which include a low-voltage model.
Guida ai test d‘isolamento diagnostici oltre 1 kV [IT] This guide discusses the causes of insulation degradation on 1kV power cables, and the process of measuring degradation before a fault can develop. The guide also recommends the best equipment to use with reference to IEEE standards. Published: 24 October • Press to start the insulation testing. The last megohm reading is displayed. Keep the leads on the test points to allow the circuit to discharge. • To perform the same timed test again, press. • To exit the timed test, hold for 2s, then use to select S, then press. The circuit under test must be switched off, de-energised, isolated and checked to be safe before insulation test connections are made. Make sure the circuit is not reenergised whilst the instrument is connected. Only Megger supplied test leads must be used. Circuit terminals must not be touched during an insulation.
