Megger MIT1525-UK 15 kV Diagnostic Insulation Resistance Tester

Megger MIT1525-UK 15 kV Diagnostic Insulation Resistance Tester

Offering CAT IV safety, the MIT1525 is compact, light 15 kV insulation resistance tester for the diagnostic testing and maintenance of high voltage electrical equipment. It benefits from the Megger dual case construction, Tough on the outside and fire retardant on the inside.

As well as measuring insulation resistance to 30 TΩ, the MIT1525 also offers various diagnostic tests such as Polarisation index, Dielectric Absorption Ratio, Step Voltage, Dielectric discharge and ramp testing.

Now equipped with lithium ion fast rechargeable batteries, the instrument has a large, clear, easy to read, display making it equally suitable for use in both bright sunlight and poorly lit environments. Information displayed includes resistance, voltage, leakage current, capacitance, battery status and time constant. In addition, the elapsed time of the test is displayed constantly removing the need for separate timer.

Features

Insulation resistance up to 30 TΩ @ 10 kV enables installation testing and long-term trending of higher value apparatus, typically above 1 TΩ
High altitude operation up to 3000 m while maintaining CATIV 1000 V (15 kV)
5% accuracy all the way up to 3 TΩ @ 15 kV ensures highest accuracy where it matters most
IR, timed IR, DAR, PI, DD, SV and ramp tests maximize diagnostic testing capability
3 mA short circuit current with unique max power regulations technology ensures maximum transfer whatever the load until selected voltage is reached
Noise filter rejects up to 6 mA (15 kV) noise for effective operation in electrically noisy environments
Li-ion battery allows up to 6 hrs continuous testing @ 5 kV with a 100 MΩ load; battery meets IEC 62133
Dedicated voltmeter function (30 V to 660 V) allows the user to check for induced volages
Smaller size and lighter weight allows easier transport and use without compromising performance
Unique dual case design allows for fire-retardant protection while maintaining ruggedness
High-quality, flexible silicon test leads meet safety regulations of IEC 61010-31:2008
Timed IR plus PI, DAR, DD, SV and ramp tests maximize diagnostic testing capability
Operate from line power even if the battery is fully discharged (charges while operating)
Two and half hour full battery charge time (one-half hour charge for one hour testing)
Up to six hours continuous testing (5 kV) on a single battery charge
Large backlit LCD clearly shows analog and digital readings
Industry best guard terminal performance to insure highest accuracy of measured values
Enhanced driver technology provides plug-and-play when connected to the internet
Rotary switch operation for easy, intuitive field use
Locking test leads provide additional safety
Date and time-stamped test results reduce the risk of error in result interpretation
