Description
The ABB SPAD346C3 is a stabilized differential relay used for protecting electrical equipment like power transformers, generators, motors, and lines. It operates by comparing the currents entering and exiting the protected equipment, and tripping if the difference exceeds a set threshold. This indicates a fault within the equipment.
Here are some key features of the ABB SPAD346C3:
- Three-phase differential protection: It can monitor the currents in all three phases of the equipment.
- Microprocessor-based: This allows for precise and reliable operation, as well as advanced features like programmable settings and communication capabilities.
- High immunity to interference: The SPAD346C3 is designed to resist interference from other electrical signals, ensuring accurate operation even in noisy environments.
- Compact size: It is a relatively small and lightweight relay, making it easy to install in space-constrained applications.
