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 UC 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 parameters like ‘Number of tests, stew time and stir time’ set in advance. Various status indicators like Power on, HV rise, HV fall, Stir and static are provided. Countdown of stew time and stir time is displayed. Audio beep is given after the test is complete and the results can be printed on built- in printer. Further the readings can be recalled after the test.
