Megger MIT 525/2 Advanced 5KV Insulation Tester

The Megger MIT 525/2 Advanced is engineered for high-performance insulation resistance testing in demanding electrical environments. With test voltages up to 5 kV and resistance measurement into the TΩ range, it is ideal for verifying the integrity of equipment such as high-voltage cables, power transformers, switchgear, motors/generators, and high-voltage bushings. 
Large business procurement teams will appreciate its rugged dual-case design (for extra protection), IP65 rating with the lid closed and CAT IV safety rating at all terminals. Small and medium business owners or maintenance contractors will value the battery/AC mains operation flexibility, rapid-charge li-ion battery, and simplified user interface. 
Diagnostic capabilities include Polarisation Index (PI), Dielectric Absorption Ratio (DAR), Dielectric Discharge (DD), Step Voltage (SV) and Ramp Test modes. Including RE>Act mode for enhanced accuracy and safety — enabling advanced fault detection beyond basic insulation resistance. 
On-board memory allows time-and date-stamped results, whilst the USB and Blue tooth interface supports data transfer to PC for logging and integration into asset-management systems (such as Megger’s PowerDB).  

Examples of applications and industries:

• Electrical utilities: testing HV cables and switchgear during maintenance outages
• Manufacturing plants: verifying insulation on large motors and generators to avoid downtime
• Renewable energy: inspecting wind-turbine cable insulation and transformer bushings
• Rail and transport infrastructure: preventative testing of overhead line or traction components
• Commercial building services: high-voltage cable and distribution board insulation verification
