MIT510/2, MIT520/2 and MIT1020/2
5-kV and 10-kV Insulation Resistance Testers
DESCRIPTION
The new MIT510/2 and 520/2, 5-kV and MIT1020/2, 10-kV
insulation resistance testers are all designed specifically to
assist the user with the testing and maintenance of high
voltage equipment. The instruments are designed in a
landscape style which is more familiar and user friendly.
The MIT510/2 and MIT520/2 measures to 15 TΩ, replacing
the ambiguous “infinity” reading with an actual number
that can be used for predictive/preventive trending on the
highest quality insulation. Both units are supplied with test
leads with medium insulated clips.
The MIT510/2 has the facility to set the test voltage in
steps from 250 V to 5000 V and the MIT520/2 has the
ability to set the test voltage from 50 V to the maximum
output voltage.
The MIT1020/2 offers a measurement range to 35 TΩ in
order to provide trending values for the best of insulating
materials used on the higher capitalized equipment. The
model features an expanded test voltage range from 50 V
to 10 kV, in 10 V increments to 1 kV and 25 V increments
above. The MIT1020/2 is supplied with two sets of test
leads, one with medium insulated clips and the other with
large insulated clips.
All three instruments have a large, easy-to-read backlit LCD
making them 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 is displayed constantly, removing the need for
separate timers. The MIT520/2 and MIT1020/2 allow up to
3 timed measurement positions to be set, which simplifies
DAR testing.
A built-in integral timer starts automatically at the
beginning of a test, and displays in minutes and seconds.
At the end of any test, capacitive loads are automatically
discharged and the decaying voltage displayed. The timer
enables the performance of an automatic IR test with the
MIT510/2, while the MIT520/2 and MIT1020/2 add the
capability of preprogrammed DAR, PI, SV and DD. The
MIT520/2 and MIT1020/2 include a selectable breakdown
or burn mode and an alarm mode, which allows the
operator to preset a specific resistance level. The unit will
beep until the limit is exceeded. The controls of the
instruments are clear and unambiguous, and a “quick start”
guide is included in the lid, eliminating the need to carry
manuals to site locations.
Redundant safety features make the instruments fully
amenable to safe operation in the more demanding high
voltage environment. The CAT IV 600 V safety rating
means that the instruments are protected for use on
outside applications and are protected against impulses to
8 kV.
for arc-flash protection. If the instrument is accidentally
connected to a live test item, external voltage will be
automatically displayed and testing inhibited above 50 V
(80 V on MIT1020/2). At the conclusion of a test,
dangerous static voltage on the test item is automatically
discharged and monitored on the display. All three models
are fitted with a guard terminal to enhance accuracy. The
guard test lead is included as standard with each
instrument.
