What do Longitudinal Tie breakers isolate?

• A. Differing voltage levels
• B. Switchboards between different zones
• C. Emergency power supplies
• D. Operational test circuits

Answer: (B)

Longitudinal tie breakers are specifically designed to isolate switchboards between different zones within a power distribution system. The primary function of these devices is to manage and maintain the separation of electrical systems, ensuring that faults or disturbances in one zone do not propagate to others, which can help in maintaining operational integrity and safety. By isolating switchboards across different zones, longitudinal tie breakers contribute to enhanced reliability and facilitate maintenance without the need to shut down entire systems. This zoning helps in localizing issues, which allows for quicker resolution and minimizes the impact on the overall electrical distribution network. In contrast, while differing voltage levels, emergency power supplies, and operational test circuits are important aspects of electrical systems, they are not the specific focus of longitudinal tie breakers. The role of these breakers is closely tied to the management and protection of switchboards across zones rather than addressing voltage discrepancies or managing power supplies directly.
