Linear load
BSRIA Power quality guide (AG 2/2000) was written by C C Pearson and V Uthayanan and published by BSRIA in July 2000. It states:
A load is said to be linear when the current it draws has the same waveform as the supply voltage (i.e. both are sinusoidal waveform, see Figure 32). Such current has no harmonic components. Examples of such loads are resistors in electric heaters, and inductive loads under steady state condition (motors, transformers, etc.). A linear load may have a phase shift F, as shown in Figure 32.
