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 its dissipation factor (tan δ or tangent delta), 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 60247:2004 and GOST 6581-75. We have designed our testers with a built-in memory for the measurement results storage, PC-connection capability, and robust operator safety systems for all-round operator protection.
