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 designed to be used with the ABB Relion® protection and control platform.
The SPAD346C uses a combination of current and voltage measurements to detect faults. The current measurement is used to detect winding short-circuits, while the voltage measurement is used to detect interturn faults. The relay also has a number of features that help to prevent nuisance trips, such as harmonic restraint and overcurrent blocking.
Here are some of the key features of the ABB SPAD346C:
- Protection against winding short-circuits, interturn faults, and earth faults
- Can be used with two-winding power transformers and generator-transformer units
- Interwinding short-circuit protection for generators
- Uses a combination of current and voltage measurements
- Harmonic restraint and overcurrent blocking features
- Compact and modular design
- Easy to install and commission
- Reliable and long service life
