An Insulation Resistance (IR) test is a qualitative test that indicates the effectiveness of a product’s electrical insulation. Applications include cables, transformers, motors/generators, circuit breakers and bushings. The IR test is ideal for measuring and recording long term stability of insulation over time, a process known as trending.
The Megger MIT525 5kV Insulation Resistance Tester’s rugged case provides ultimate protection for a portable instrument and a clip-on lead pouch ensures that leads remain with the instrument at all times. The case lid is removable for improved terminal access. IP rating is IP65 with the case closed preventing entry of water and/or dust. High reliability and safety are built in, as the Megger MIT525 is safety rated to CATIV 600 V and double insulated.
Five preset voltage ranges are provided in insulation test mode, plus a user settable lock voltage range. Preconfigured diagnostic tests include Polarisation Index (PI), Dielectric Absorption Ratio (DAR), dielectric discharge (DD), Stepped Voltage (SV) and ramp test.
The MIT525 also offers simplistic operation with two rotary switches and a large backlight display enables multiple results to be displayed simultaneously.
Advanced memory storage for the MIT525 includes time/date stamping of results, logging of data and recall of results to screen. A fully isolated USB device interface (type B) is used for safe transfer of data to Megger’s PowerDB / Pro, Advanced and Lite asset management software.
The MIT525 offers advanced features and rapid charge capability, with a range consisting of 5 kV and resistance measurement up to 10 TΩ. A key feature of the MIT525 is the ability to take measurements when connected to line power/mains with a dead battery.
