heal.abstract Partial discharges are a common phenomenon on the power lines of the electrical network. This paper presents the occurrence of sparks and external partial discharges on insulators and the conditions under which they take place. Furthermore, it is investigated the probability of the appearance of sparks on bare conductors of low and medium voltage and the external factors, as humidity and pollution, which affect this phenomenon. Finally, it is estimated that the thermal stress of a wooden crossarm on a pylon of medium voltage could not lead to the ignition of the crossarm. For its ignition, overextended humidity and a very contaminated environment is required. en
