The Megger Oil Tan Delta (OTD) is a laboratory instrument, which measures the Tan Delta, Resistivity and Relative Permittivity of insulating liquids.  These tests give a wider picture of the overall quality of the insulating oil, and will indicate if there is any contamination. Megger has developed features of the OTD to ensure that productivity levels within laboratories are maximised.

Monitoring and maintenance of oil quality is essential to ensure the reliable operation of oil filled electrical equipment. Codes of practice have been established in many countries that include tests for Tan Delta, Relative Permittivity and Resistivity.

User safety is paramount and Megger have designed independent, dual redundant high voltage cut-off circuitry to ensure safety. During a test, press any button on the keypad to remove the high voltage immediately and abort the test.

The OTD has a 12 key alpha-numeric keypad to facilitate entry of test ID, filenames, notes, etc.
