Multi-parameter oil analyzer: conductivity, resistivity, dielectric loss
PE-AORDF-1
Power Electronical
PE-AORDF-1 Fully Automatic Oil Resistivity & Tan-delta tester is a 2-pc unit, consisting of Heater unit and Measuring Bridge. The Stainless Steel oil cell is to be mounted inside the Heater unit. Heater unit is separated from main unit, to avoid component derating and influence of temperature on measurements Measuring Bridge consists of AC/DC high voltage supply, Tera-ohm meter, and precision electronic bridges to measure & derive the readings for

Oil suffers from electrical and mechanical stresses while a transformer is in operation. In addition there are contaminations caused due to chemical interactions with windings and other solid insulations, catalyzed by high operating temperature. As a result the original chemical properties of Transformer Oil changes gradually, rendering it ineffective for its intended purpose after many years. Hence this oil has to be periodically tested to ascertain its basic electrical properties, and make sure it is suitable for further use, or necessary filtration/regeneration has to be done.
