Lightweight, portable unit for field use
Simple, semi-automatic operation
Suitable for all oil breakdown testing to 60 kV
Automatic 1 minute timer for easy withstand testing
The OTS60SX is a lightweight, semi-automatic, oil dielectric strength test set. The instrument is suitable for field use and is powered from a range of line voltages. The maximum 60 kV output allows tests to be performed on oil from a wide variety of electrical installations including transformers, circuit breakers and other equipment.
Oil has been used as an insulating medium in transformers for over one hundred years. From the earliest days of transformer design, oil has been recognised as being an efficient coolant with a high flash point and high electric strength. Oil can be used in electrical equipment for a long time if adequately maintained. Many factors can lead to a weakening of the insulation properties of oil. Oil degradation takes place due to oxidation, acids, sludge, gas and water absorption. These processes change the electrical properties of the oil which can be seen from a dielectric strength test. The range of oil test sets available from Megger Limited offers solutions for all oil testing applications. The popular OTS60PB is a fully automatic portable unit. The automatic, laboratory OTSAF/2 series incorporate a built in printer and enable the user to program custom tests.
