Insulation resistance testing is used to evaluate the integrity of insulation, and can be used for:
– A quality control measure at the time a piece of electrical equipment is produced
– A periodic preventive maintenance task
– A troubleshooting tool
The Megger MIT525 and Megger MIT1025 both provide five preset voltage ranges in insulation test mode, plus a user settable lock voltage range. Preconfigured diagnostic tests include Polarization Index (PI), Dielectric Absorption Ratio (DAR), dielectric discharge (DD), Stepped Voltage (SV) and ramp test.
Advanced memory storage in The Megger MIT525 and Megger MIT1025 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 asset management software.
Each Protec office stocks a full complement of Insulation resistance, electrical test and measurement equipment.
