Megger’s OTS80PB and 60PB Oil Test Sets are portable liquid dielectric breakdown testers. They are fully automatic, powered by battery/mains and facilitate accurate breakdown voltage tests on mineral, ester and silicon insulating oils. Used on site as well as in the laboratory, the precision test vessel sets the accuracy standard for the liquid insulation test industry. For ease of use the instruments comes pre-programmed with a ‘library’ of international breakdown test standards and the ability to create custom tests.

Megger’s automatic portable oil test set OTS80PB performs accurate breakdown voltage tests on mineral, ester and silicon insulating liquids. Moulded test vessels give repeatable results in the field and laboratory with lock in precision electrode gap setting adjustment wheels. The transparent, shielded lid is a key feature enabling users to see what is happening within the test chamber.

The OTS80PB is line powered with the option of internal batteries (either Lead Acid, NiMH or no battery) but the OTS60PB only offers NiMH battery or no battery option. In addition to line power charging, a 12 V DC charger facility is factory fitted with either battery option.

Megger portable 60 kV and 80 kV oil test sets are the lightest on the market ranging from 16 kg to 23.5 kg depending on model and configuration. They come complete with optional carry bag and transport case.
