Introduction:

Insulating oil being an efficient cooling medium with high dielectric strength has been a recognized insulating medium in electrical equipments. Degradation of oil takes place due to acids, oxidation, sludge, gas and water absorption. A dielectric strength test shows the changes caused in oil due to these processes. 'UDEY' Series CU insulating oil testers are fully automatic microcontroller based testers completely self contained with built in printer. 'UDEY' insulating oil testers are the industry standard for over 47 years.

System Description:

The system is fully automatic and carries out tests according to the set or chosen menu like ‘Number of tests, Settling time, Stir time and Waiting time’. System time, setting of test parameters, status and data is displayed on LCD. Audio beep is given after the test is complete and the results can be printed on built-in printer. The test results can be recalled for view after the test. Further the last 99 test readings can also be recalled and printed.
