Overview
Product series SPRECON-E-P D..4/D..6-1/D..6-2
The digital SPRECON protection devices SPRECON-E-P D..4, SPRECON-E-P D..6-1 and the combined protection and control devices SPRECON-E-P D..6-2 are used for protection of power lines, cables, transformers and motors. The devices have been developed for all significant grid and neutral-point connections at high and medium voltage levels.
SPRECON-E-P series:
- Protection devices
- Combined protection and control devices
- Dual-powered protection devices
- Directional earth fault protection device (transient-based)
- Capacity release unit
The SPRECON-E-P D..6-2 devices are one-box solutions for protection and control, which allow protection of primary equipment by simultaneously accomplishing control and monitoring functions in electric power systems.
They feature a clear separation of control and protection which allows either combined or separated operation of control and protection functions:
- Separated data models
- Separated control and protection firmware
- Separated control and protection configuration
- Separated passwords
The devices are distinguished by their modular design and highest flexibility and scalability. Due to the consequent platform-approach, all modules of the SPRECON-E devices can be used.
Standard protocols (IEC 61850, IEC 60870-5-103, IEC 60870-5-104) as well as proprietary protocols allow communication between different control systems.
All products can be controlled and configured with Sprecher’s user-friendly protection software SPRECON-E COMM-3.
