5 kV and 10 kV Insulation Resistance Testers
DeSCRIPTIOn
The new 5 and 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 MIT1020/2 facilitates this.
The case is incredibly rugged and easy to carry, being made
of tough polypropylene and achieving an ingress protection
rating of IP65. In addition, the model number is marked on
both sides 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. Adjustable timers and limit alarms are
included.
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 required.
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 the
instrument.
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 application needs.
These IR instruments are designed to meet the highest safety
standards and meet 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 phase.
The MIT520/2 and MIT1020/2 are equally suited to routine
testing and diagnostic regimes being pre-programmed with
IR, PI, DAR, SV and DD profiles.
