ABB TTR 6x Medium Voltage MV Indoor Bushing CT's

Up to 25kV 

 

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.
