frequency variations

Frequency variation refers to changes in the rate at which electrical or electromagnetic waves oscillate. In power systems, it indicates how fast the electrical cycle completes a full wave (measured in Hertz). When supply and demand are balanced, frequency remains stable; however, if demand exceeds generation, the frequency drops, and if generation exceeds demand, it rises. Such fluctuations can impact equipment performance and system stability. Monitoring and controlling frequency variations are essential for maintaining reliable electrical supply and ensuring machinery operates correctly within designed specifications.
