Megger OTS80PB

The Megger OTS80PB is an advanced automatic oil test set designed to perform precise breakdown and withstand voltage tests on mineral, ester, and silicone insulating liquids. Its robust design incorporates shatter-proof test vessels that are both easy to clean and capable of delivering repeatable results, whether used in laboratory settings or on-site in the field. Equipped with a transparent, shielded lid and a spacious test chamber, the OTS80PB ensures optimal visibility and ease of access during testing procedures. Each test result is serial number or asset ID tagged, time-stamped, and can be seamlessly managed using PowerDB Lite, Megger’s custom asset and data management software, included at no extra charge. An integrated printer also provides instant hard copy outputs for added convenience.

To prioritise operator safety, the test set allows immediate termination of a test by pressing any keyboard button, automatically removing high voltage and aborting the test. The transparent lid is electrically shielded for enhanced safety while monitoring the testing process. With globally pre-loaded testing standards and customisation options for new requirements, the Megger OTS80PB ensures uncompromised compatibility and performance.
