The paper proposes a methodology to model the impulse rate of sporadic impulsive noise, namely the impulsive noise that is generated by the transients during the on/off switching of electrical appliances. In particular, it is proposed to exploit the publicly available datasets of power consumption measurements campaigns to derive the instants when a switching on/off event occurs. The statistics of the impulse rate is derived considering the data gathered during a six-month measurement in one of the houses of the GREEND dataset. Furthermore, to define the set of appliances that generate sporadic impulsive noise within the considered house, a noise measurement campaign at the source the corresponding analysis was carried out.
