How Do Substations Work? — Practical Engineering
As a junction point in the grid, a substation often serves as the termination of many individual power lines. This creates redundancy, making sure that the substation stays energized even if one transmission lines goes down. But, it also creates complexity. The connections to these various devices are called buses, often rigid, overhead
What is a circuit breaker, and how does it work?
A circuit breaker is an electrical switching device designed to protect an electrical circuit from damage caused by excessive current flow. Its primary function is to interrupt the circuit''s current flow when it detects an overcurrent or a fault condition, preventing potential fire hazards, equipment damage, and electrical system failures.
3AH3 Vacuum Circuit-Breakers
