The Megger OTS60PB is a fully automatic, battery powered, portable oil test set. The test voltage is electronically controlled to the maximum of 60 kV. Designed for on site testing, the instrument is supplied in a rugged carrying case with a handle for ease of transportation. An internal rechargeable battery gives a large number of tests before recharging. A clear display shows a menu of test options and guides the operator through the set up programme, illustrates the correct test electrodes and gap to use, shows the progress of each test and gives the results of the test sequence. The result can be set to give either a numerical average (with standard deviation where specified) or a pass/fail message. The display on the Megger OTS60PB Oil Test Set can be set to read in English, French, German, Italian, Spanish and Portuguese.

An optional printer kit for the Megger OTS60PB oil test set enables hard copies of results to be produced. Accessories, such as the battery charger, spare vessels, spare electrodes and a spacing gauge are located in an attached compartment. Stirring is carried out by a motor driven paddle stirrer.

General information about Oil for Transformers, Switchgear and other Electrical Apparatus
Oil has long been recognized as being an efficient coolant with a high flash point and high electric strength when used as an insulating medium in transformers, switchgear and other electrical apparatus. It is critical, however to maintain the oil properly to avoid weakening of the insulation properties.

The electrical properties of the oil can change with degradation due to oxidation, acids, sludge, gas and water absorption. These changes can be identified through a dielectric strength test. Megger Oil Test Sets are designed specifically to determine the dielectric strength of insulation oils.
