NERC System Operator (SOS) Exam 2025 – 400 Free Practice Questions to Pass the Test

Question: 1 / 465

What can be a consequence of not managing voltage control equipment during transmission outages?

Increased power generation

Uncontrolled voltage fluctuations

Managing voltage control equipment effectively during transmission outages is crucial for maintaining system stability and reliability. When voltage control equipment is neglected, one significant consequence can be uncontrolled voltage fluctuations.

These fluctuations can lead to various operational issues, including stress on electrical components, increased losses in the system, and compromised reliability. Uncontrolled voltage levels can cause equipment to operate outside of their designed parameters, potentially leading to equipment damage or failure. It may also result in cascading failures, affecting a larger portion of the electrical grid and leading to outages.

Unlike improved system stability or increased power generation, which may not result from neglecting voltage control, uncontrolled voltage fluctuations are a direct and critical outcome that impacts the overall health of the power system.
