Insulation Resistance Testing
AVO International Major MEGGER Insulation Resistance Tester
The Major Meggers have been designed for convenience and ease-of-use when testing complex or larger electrical installations, and commissioning, servicing or maintaining electrical equipment. They are designed for the safe testing of motors, generators, cables, switchgear, transformers, distribution networks, industrial and domestic installations, components and appliances.

The instruments are suitable for testing installations to the requirements of most international wiring regulations including the IEE Wiring Regulations and the German Regulations VDE 0100. To achieve this, an instrument's performance on the resistance ranges fully conforms to VDE0413 parts 1 and 4.

The range of insulation test voltages available allows one instrument to be used for a variety of applications. For example, installations and equipment can be tested at 1000 V d.c. when this requirement is specified. Also aircraft and telecommunications equipment can be tested at the relatively low 100V d.c. and 110V to 120V a.c. systems can be tested using 250V d.c.
