DESCRIPTION
APPLICATION
Megger’s automatic laboratory oil test sets perform accurate
breakdown voltage tests on mineral, ester and silicon insulating
liquids. Moulded test vessels give repeatable results with lock in
precision electrode gap setting adjustment wheels. The transparent,
shielded lid and large test chamber enable easy access to the test
vessel.
Monitoring and maintenance of oil quality is essential in ensuring
the reliable operation of oil filled electrical equipment. Codes of
practice have been established in many countries that include
several different types of test on insulating oils.
All three laboratory models are fitted with a 12 key alpha-numeric
keypad to facilitate entry of test ID, filenames, notes etc. Alpha
characters are entered by repetitive pressing on a key, the same way
as text is entered modern cellular telephones.
Test standards are preloaded in the instrument and new versions
can be uploaded via USB flash drive. All laboratory models support
the creation of user defined custom tests. Test results are identified
either by a serial number or asset ID and are time and date
stamped. Megger’s asset and data management software, PowerDB
Lite, is bundled at no extra cost providing an excellent tool for
downloading and printing results.
An optional internal printer provides a hard copy of results. Ink
based printout ensures durability at all temperatures. USB interfaces
(x3), USB flash drive, external USB printer and barcode scanner.
User safety is paramount and Megger have designed independent
and dual redundant high voltage cut-off circuitry to ensure safety.
During a test the operator can terminate by pressing any button
on the keyboard which will remove high voltage immediately and
abort the test. The transparent lid provides ample visibility within the
chamber yet is protected and electrically shielded by a screen with
multiple links to instrument ground.
One of the fundamental tests of oil quality is the breakdown
voltage test, which is a measure of the oil’s ability to withstand
electric stress. A low breakdown voltage can indicate the presence
of contaminants such as water or conducting particles.
Care should be taken to ensure the process of sampling oil and
subsequent testing does not in any way contaminate it with foreign
objects. Cleaning vessels between oil tests should be a rinse with
the next sample, never clean with fibrous materials. To ensure an
accurate reading set gap carefully and lock adjusting wheels.
