DielectricLossTester

Oil suffers from electrical andmechanical stresseswhile 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

propertiesofTransformerOilchangesgradually,renderingit

ineffectiveforitsintendedpurposeaftermanyyears.Hence

this oil has to be periodically tested to ascertain its basic

electricalproperties,andmakesure it issuitableforfurther

use,ornecessaryfiltration/regenerationhastobedone.

PEAORDF Precision Automatic Oil Resistivity & DielectricLoss Tester is a highly precise instrument, which can beapplied to measure Resistance, Dissipation Factor, and
