Description
The ABB SPAD346C is a stabilized differential relay module that provides winding short-circuit and interturn fault protection for two-winding power transformers and generator-transformer units, and interwinding short-circuit protection for generators. It is a retired product, but it is still in use in many power plants around the world.
The SPAD346C has the following features:
- High accuracy and sensitivity
- Fast operating times
- Immune to inrush currents and harmonics
- Can be used with a variety of transformers and generators
- Easy to install and maintain
The SPAD346C is a modular device that consists of a main relay unit and up to four auxiliary modules. The main relay unit contains the differential protection circuits, while the auxiliary modules provide additional features such as overcurrent protection, earth fault protection, and communication interfaces.
