What is the primary function of a throttle bar in substations?

The primary function of a throttle bar in substations is to control the opening and closing of bus bars. The throttle bar acts as a mechanism that allows operators to manage the electrical flow within the substation efficiently. Bus bars serve as metal bars that conduct electricity, distributing power to different circuits. By controlling these bus bars, the throttle bar helps maintain safety and operational efficiency in the substation, preventing overload conditions and facilitating maintenance activities.

This function is critical since improper handling or malfunctioning of bus bars can lead to significant disruptions in power distribution or even equipment damage. Understanding the role of components like the throttle bar is essential for ensuring the safe and reliable operation of substations.
