The new 5 & 10 kV insulation resistance testers from
Megger are designed specifically to assist you with the
testing and maintenance of high voltage electrical
equipment. IEEE 43-2000 recommends the use of 10 kV
for motor windings rated above 12 kV and the Megger
MIT1020 facilitates this. The case is incredibly rugged and
easy to carry, being made of tough polypropylene and
achieving an ingress protection rating of IP54. In addition,
the model number is marked on both the top and side of
the case for ease of identification in stores or vehicles.
The instruments have a large easy to read backlit LCD
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 timers.
The instrument can test when being powered by the
mains or its internal rechargeable battery, a great benefit
when site conditions are unknown or long term testing is
The controls of the instrument are clear and unambiguous
and a “quick start” guide is included in the lid of the
instrument removing the need to carry bulky manuals
under site conditions.
The instrument is fitted with a guard terminal to enhance
accuracy. The guard test lead is included as standard with
To further enhance the flexibility of the instruments both
have the facility to set the test voltage in steps from 50 V
to the maximum output voltage avoiding the expense of
several insulation resistance testers to meet your
These IR instruments are designed to meet the highest
safety standards and meets the requirements of EN61010.
In addition, the instrument measures the voltage at the
terminals and if this is above 50 V then the instrument will
display the high voltage warning and inhibit testing. At the
end of the test the instrument will automatically discharge
the energy transferred to the equipment during the test
The MIT520 and MIT1020 are equally suited to routine
testing and diagnostic regimes being pre-programmed with
IR, PI, DAR, SV and DD profiles.
