What is the purpose of electrical interlocking in specific installations?

The purpose of electrical interlocking in specific installations is to prevent multiple non-synchronized power sources from energizing a single bus. This is crucial in maintaining system integrity and safety. By ensuring that only one power source can connect to a bus at any given time, interlocking mechanisms help avoid dangerous situations such as electrical faults, potential equipment damage, or even catastrophic failures. It effectively facilitates safe operation by preventing scenarios where two or more sources could inadvertently try to supply energy simultaneously, which could cause significant disruptions, fires, or electrical hazards. Therefore, the use of interlocking contributes significantly to the creation of a reliable and safe electrical environment in various applications.
