Tumble Drier: (power/time)
The signature is made up of two distinctive sections; the main cycle and the end of the cycle.
During the main cycle, the power draw alternates between 2000 and 200 W over a duration of between 100 and 140 minutes. The reason this is not represented consistently between the plots is due to the periodicity of sampling. Power values are only sampled at minute intervals, so any alternations between samples are not recorded.
The second section constitutes the final sixth of the appliances operation. Although this section is consistent on three of the four graphs, one plot still captures alternation of the power drawn.
