What happens if jumper placement is incorrect?

When jumper placement is incorrect, it can lead to an increase in resistance. This is because jumpers are designed to provide a low-resistance path for electrical currents. If they are not installed correctly, the pathways they create may introduce additional resistance into the circuit. This increased resistance can affect the performance of the electrical system, causing various issues such as voltage drops, inefficient operation, and overheating of components.

In a substation, where precise control and distribution of electrical power are critical, any increase in resistance can disrupt the balance and efficiency of the system. It can lead to components not receiving the adequate voltage or current they require, which may hinder their function and reliability.

The other potential outcomes listed involve different scenarios that are not directly tied to the main concern of jumper placement. While current flow being stopped and insulation failure can be serious issues in an electrical system, they are typically more related to circuit breaks or overloads rather than the incorrect placement of jumpers.
