Function of 7UT612 Transformer differential protection

The SIPROTEC 7UT612 relay differential insurance mathematical transfer is utilized for quick and specific shortcomings getting free from short circuits in transformers of all voltage levels and furthermore in turning electric machines like engines and generators, for short lines and busbars. The insurance transfer can be defined for use with three-stage and single-stage transformers. The particular application can be picked by definition.

Along these lines, an ideal adaptation of the hand-off to the secured article can be accomplished. Notwithstanding the differential capacity, a reinforcement overcurrent insurance for 1 winding/star point is coordinated into the transfer. Alternatively, a low or high-impedance limited earth issue assurance, negative grouping insurance, and a breaker disappointment security can be utilized. With outside temperature observing boxes (thermo-boxes) temperatures can be estimated and checked in the transfer. Consequently, complete warm observing of a transformer is conceivable, for example problem area computation of the oil temperature.

The SIPROTEC 7UT612 relay gives simple-to-utilize neighborhood control and robotization capacities. The coordinated programmable rationale (CFC) permits the clients to execute their own capacities, for example for the robotization of switchgear (interlocking). Client characterized messages can be produced as well.The adaptable correspondence interfaces are open for modem correspondence structures with the control framework. The assurance transfer can be defined for use with three-stage and single-stage transformers. Likewise, a warm imitation is incorporated for the oversight of the ohmic misfortunes in the plant.
