Dielectric oil testers provide measurements of the breakdown voltage of insulating oils used in electrical equipment like transformers, switchgear, capacitors, and a variety of other essential electrical and substation components. ATEC offers a variety of testers for rental from top manufacturers such as
High Voltage Inc.,
Hipotronics, and
Megger.
Oils which possess both a high flashpoint and high dielectric strength (
dielectric meaning transferring electrical energy without conduction) are used for cooling and serve as essential insulating elements in electrical components. Testing the breakdown voltage of the insulating oils helps assess their condition, the quality of the refining, the purity of the oil, aging, and dielectric losses. Dielectric oil testers are easy to set up and provide precise, accurate, and reproducible results.
