Oil dielectric dissipation factor meters

During the normal operation, the insulating oil may get contaminated with colloidal impurities, organometallic compounds, particles of solid insulation and various aging by-products. The degree of contamination of liquid dielectrics can be determined by the value of it’s the dissipation factor (tan δ), while the dependency of the dissipation factor on the temperature of the liquid can help identify the type of such contaminants.

High-accuracy TANGENT-3M testers from KharkovEnergoPribor Ltd. are used for automated measurement of dissipation factor of insulating oils according to IEC 60247 and GOST 6581-75. We have designed our testers with a built-in memory for measurements results storage, PC-connection capability, and robust operator safety systems for all-round operator protection.
