What is primarily affected by harmonic distortion in a power system?

Harmonic distortion primarily affects signal integrity in a power system because it introduces unwanted frequencies that can interfere with the normal operation of electrical devices and communication systems. When harmonics are present in a power system, they can distort the waveform of the voltage and current signals, leading to inaccuracies in measurement and degradation of performance in sensitive electronic equipment. This distortion can cause issues such as increased heating in conductors, malfunctioning of electronic devices, and erroneous readings in metering systems.

Maintaining signal integrity is crucial for the reliable operation of systems that rely on precise electrical signals, such as data communications and control systems. Therefore, understanding and mitigating harmonic distortion is vital to ensure that the integrity of these signals is preserved, ultimately leading to improved performance and efficiency in electrical systems.
