Oil suffers from electrical and mechanical stresses while a electrical equipment 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 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 has to be done. The most common and easiest test of these is finding out the breakdown or flashover potential of the Oil under test. PE-LOBDV series of Oil Breakdown Tester are available in a variety of maximum test voltages, denoted by their suffixes
PE-LOBDV is a motorized (Automatic) oil test instrument, which is precise and is applied to accurately measure the dielectric breakdown voltage of the Oil under test. It consists of the high AC voltage generating unit, and the Oil vessel (as per applicable standard)
