The K Factor is a crucial parameter in electrical systems, particularly in the context of transformers and power systems involving non-linear loads. It specifically indicates the level of harmonic distortion within the electricity distribution system. By definition, the K Factor helps in assessing how much the non-linear loads will cause heating in the electrical equipment.

When the K Factor increases, it illustrates a higher level of harmonic currents generated by non-linear loads. This increased activity generates additional heat in systems, primarily because such loads may introduce varying current wave shapes which deviate from the standard sinusoidal waveform. The equipment designated with a higher K Factor rating means it can handle these higher levels of harmonics with appropriate thermal limits, effectively increasing physical tolerance of components like transformers and conductors against the additional heating effects caused by harmonic currents.

This understanding ties directly to how electrical systems are designed to accommodate these nonlinear loads while maintaining safety and efficiency. Hence, the correct response highlights the importance of physical tolerance in accommodating the effects brought about by harmonic distortion.
