Implementation of Cross and Longitudinal Connections (30/66 kV)

Cross and longitudinal connections in 30/66 kV distribution and sub-transmission networks are essential for improving system reliability, flexibility, and continuity of power supply. These interconnections allow load transfer, fault isolation, and network optimization, especially in complex and expanding grid systems.

This 10-day advanced training program, developed by Global Horizon Training Center, provides a comprehensive understanding of the design, implementation, operation, and protection of cross and longitudinal connections in medium- and high-voltage networks.

Participants will gain practical expertise in planning network interconnections, ensuring protection coordination, managing switching operations, and maintaining system stability and safety.

By the end of this program, participants will be able to:

• Understand the concept and importance of cross and longitudinal connections
• Design and implement interconnection schemes in 30/66 kV systems
