MEG10-01

10 kV Insulation Tester

DESCRIPTION

The Megger MEG10-01 is a compact, microprocessor
controlled high voltage d.c. insulation tester, which may be
powered by internal rechargeable batteries or by
connection to an a.c. supply. It is built into an extremely
robust moulded case with internal provision for test lead
and mains power cord storage.

Measurement results are clearly displayed on the custom
digital and analogue LCD display as either an Insulation
Resistance or a Leakage Current.

The measurement range, subject to test voltage, is up to
500 GW on the digital display, and to 1TW at all voltages
on the analogue scale. Test voltages of 500V, 1000V,
2500V, 5000V and 10,000V are available and are selected
by a two buttons on the front panel.

IEEE43: 2000 "IEEE Recommended Practice for Testing
Insulation Resistance of Rotating Machinery" now offers
the option of testing machines rated above 12kV at 10 kV
instead of the previous 5kV maximum. The 10kV range
on the MEG10-01 allows this test to be easily achieved.

An integral timer is started automatically on
commencement of a test, which displays elapsed time in
minutes and seconds. This timer may also be used to
automatically stop an insulation resistance test and an
automatic Polarisation Index test. At the end of any test,
capacitive loads are automatically discharged and the
decaying voltage is displayed until it reaches a safe level.
At any point, a flashing LED and segments on the display

indicate the presence of a dangerous voltage.

The battery condition is continually monitored while the
instrument is switched on and the battery condition is
shown by a 5-segment bar graph on the display.

Power is provided by an a.c. supply or from an internal
rechargeable battery which when fully charged is capable
of providing at least 4 hours continuous testing at 10kV
before requiring recharge.

For those users who prefer to store their test results for
later download, the MEG10-01 has on-board memory
capable of storing typically 30 test summaries although this
will vary according to the type of test and test duration.
This summary information is suitable for reporting
purposes.

However, if long term testing is required with more
detailed data, the MEG10-01 outputs data over its RS232
port every second, in real time. A PC may be used to
capture this data and under these circumstances the
amount of data is limited by the amount of storage space
available on the PC. The volume of data only consumes
approximately 2.4 kB for every minute of output. This
real time feature allows detailed data to be captured for
later analysis.

APPLICATIONS

Manufacturers, users and maintainers of rotating machinery
will find the Megger MEG10-01 a perfect every day work
tool.

MEG10-01

10 kV Insulation Tester

Designed in accordance with the requirements of IEEE43:
2000 the MEG10-01 is the ideal instrument for measuring
the insulation resistance of armature and field windings in
rotating machines rated 1hp (750 W) or greater. The
standard applies to synchronous, induction and d.c.
machines as well as synchronous condensers.

The Megger MEG10-01 also performs automatic
Polarisation Index tests. This test is routinely performed
on a variety of equipment and cables to assess the general
condition of the insulation before applying a potentially
destructive applied voltage test at voltages greater than
rated voltage.
