What is the purpose of tie breakers in a power system?

The purpose of tie breakers in a power system is to facilitate the interconnection of two power sources, enabling them to operate together under certain conditions. When two power sources are connected through a tie breaker, it allows them to share the load, effectively balancing the demand and supply of electricity. This is particularly useful in maintaining system stability and reliability, as it enables operators to switch from one power source to another without experiencing outages.

By securely connecting two sources, tie breakers help in managing interdependencies between systems while ensuring that they can be operated safely and efficiently. This capability is crucial in scenarios where different power generation units (like generators or power plants) need to be synchronized for optimal operation.
