Offering CAT IV, the Megger MIT525 is compact, light 5kV insulation resistance tester for the diagnostic testing and maintenance of high voltage electrical equipment. Enclosed in a tough case it is both smaller and lighter than its predecessor making it even easier to carry and store.
As well as measuring insulation resistance to 10 TΩ, the MIT 525 also offers various diagnostic tests such as Polarisation index, Dielectric Absorption Ratio, Step Voltage, Dielectric discharge and ramp testing. The MIT1025 has a full suite of test modes as well as on-board memory and the ability to stream data/download data to a PC/laptop.
The Megger MIT525 can be powered from the mains supply or by it’s rechargeable battery, which provides for 4½ to 6 hours of continuous testing with a 100 MΩ load, depending on model. The battery pack contains Lithium-ion cells and should be replaced when it no longer holds a charge. A new battery is available as a spare part from Megger. The battery pack is housed within a grey moulded cover secured by four screws. On no account must the transparent inner case be opened. Hazardous voltages up to 10kV will be exposed.
