PCS-985BT/TW/TS/T Transformer Relay
PCS-985 transformer relay can be applied for transformer with various voltage levels and wiring modes, and provides interfaces for power plant automation. The full-integrated transformer protection integrates protection, control and monitoring functions to provide users with a comprehensive, reliable and cost-effective solution. It supports conventional CT/VT and ECT/EVT, and fully compatible with IEC-61850 communication.
For a large-scale transformer, two sets of PCS-985 protection can be used to achieve duplicated protection configuration. Two PCS-985 protections use different CT groups, and main and backup protection in one PCS-985 share one group of CTs.
- PCS-985TW is adaptive from medium to large main transformer in hydro power plant.
- PCS-985TS is adaptive to small main transformers, auxiliary transformers and startup/standby transformers in power plants. It can be used for the transformer with up to 4 branches at LV side.
- PCS-985T is adaptive from medium to large startup/standby transformers and auxiliary transformers in power plants. It can be used for the transformer with up to 8 branches at LV side.
