DCS module card components 1MRK002820-AC

DCS module card components 1MRK002820-AC

Ordering of VT inputs inside of the busbar protection IED will allow integration of voltage related functionality like undervoltage release, residual over-voltage, power functions, metering and voltage recording during the faults. However attention shall be given to the fact that inclusion of VT inputs will reduce number of available CT inputs (in total 24 analogue inputs are the product limit).

Consequently when VT inputs are ordered the busbar protection IED will be applicable for buses with a fewer number of bays. Practically the number of available CT inputs will limit the size of the station which can be protected.

The IED has very low requirements on the main current transformers (that is, CTs) and no interposing current transformers are necessary. For all applications, it is possible to include and mix main CTs with 1A and 5A rated secondary current within the same protection zone.

Typically, CTs with up to 10:1 ratio difference can be used within the same differential protection zone. Adjustment for different main CT ratios is achieved numerically by a parameter setting.
