ABB Medium Voltage MV Indoor Bushing Current Transformers CT's ABB TTR 4x MV Medium Voltage MV Current Transformers CT's 3.3kV/3.6kV - 11kV/12kV Medium Voltage MV Bushing Current Transformers ABB Power Products ABB TTR6x medium voltage current transformers are cast in epoxy resin for MV insulation up to 25kV - ABB TTR6x medium voltage transformers are configured as bar-type, with either one or more transformer ratios (possibility to change over the meddium voltage MV secondary side) and perform the function of a bushing when installed on the switchboard. The ABB TTR6x indoor bushing current transformer is designed with either 1 or 2 secondary transformer windings and depending on the combinagtion of parameters (accuracy class, burden, short circuit current, overcurrent factor) with the possibility to choose from various sizes of the medium voltage transformer. The secondary MV transformer windings are used for measurement or protection purposes - one transformer terminal of each secondary transformer winding in use and one terminal of short-circuited and not used medium voltage winding have to be earthed during the transformer operation. The seoondary windings are lead out into a cast-type secondary terminal board, covered with plastic cover which may be sealed. The ABB transformer can be mounted in any position for efficient and reliable MV medium voltage performance. The ABB transformer is fixed by using four screws. ABB TTR 4x Current Transformers CT ABB Medium Voltage MV Indoor Bushing Current Transformers CT's - ABB TTR Features Transformer rated primary medium voltages : 17.5kV to 25kV Transformer rated current : 100, 150, 200, 300, 400, 500, 600, 750, 1000, 1250, 1500, 2000 and 2500Amps Transformer rated frequency : 50 Hz ; 60 Hz (Herz) ABB indoor bushing current transformers for MV medium voltage service are conformant to following specifications : IEC, VDE, ANSI, BS, GOST and CSN.TRANSCRIPT
Description
Highest voltage for equipment
TTR 4x. xxIndoor Bushing Current Transformer
Medium Voltage Product
The TTR 4x.xx current transformers are cast in epoxi resin and designed for insulation voltages up to 12 kV.The TTR 4x.xx transformers are configurated as bar-type, with only one or more ratios (secondary side to be changeover) and perform the function of a bushing when installed in the switchboard.The transformer is designed with either 1 or 2 secondary windings and, depending on the combi-nation of parameters (accuracy class, burden, short-circuit current, overcurrent factor…) with the possibili-ty to choose from various sizes of the transformer.The secondary windings are used for measurement or protection purposes. One terminal of each secondary winding in use and one terminal of short-circuited and not used winding have to be earthed during the trans-former operation.The secondary windings are lead out into a cast-type secondary terminal board, covered with plastic cover which may be sealed.The transformer can be mounted in any position. The transformer position is fixed by using four screws.
