Monitoring and maintenance of oil quality is essential in ensuring the reliable operation of oil filled electrical equipment. One of the fundamental tests is the breakdown voltage test, which is a measure of the oil’s ability to with­stand electric stress. A low breakdown voltage can indicate the presence of contaminants such as water or conducting particles.

The Megger OTS80PB 80kV Oil Test Set utilizes an oil vessel with a lockable gap setting for high precision along with flat electrode gap gauges that will not damage electrodes. Automatic oil temperature measurement is available with the test chamber and vessel remaining visible during testing due to the transparent lid. An intuitive user interface with colour display supports fully automatic operation with preloaded international test standards plus user configurable test sequences.
