Monitoring and maintenance of oil quality will ensure reliable operation of oil-filled electrical equipment.
Breakdown voltage test is one of the fundamental tests to determine oil quality by measuring the oil’s ability to withstand electric stress.
A low breakdown voltage can indicate the presence of contaminants such as water or conducting particles in the oil.
Available in three models, Megger’s automatic laboratory oil test sets feature moulded test vessels that 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.
All three laboratory oil testers are equipped with a 12-key alphanumeric keypad to facilitate entry of data such as test ID, filenames and notes. Test results are time and date stamped.
Megger’s laboratory oil testers come preloaded with test standards and new versions can be uploaded via the USB flash drive. All laboratory models support the creation of user-defined custom tests.
Megger’s asset and data management software, PowerDB Lite is bundled at no extra cost with these oil test sets providing an excellent tool for downloading and printing results.
An optional internal printer provides a hard copy of results while the ink-based printout ensures durability at all temperatures.
Three USB interfaces support PC connection, USB flash drive, external USB printer and barcode scanner functions.
