Abstract

The correct dimensioning of the transmission line insulators requires the detailed knowledge of the site pollution level. In Hungary a new, continuously operating air pollution monitor was developed, which is suitable to characterise the endangerment of the insulators. The equipment continuously bubbles the air across an absorbing solution, determines the instantaneous change of conductivity and expresses the soluble ammount of the pollution in equivalent NaCl /lg/air rn3 • The continuous measurement results the probability distribution function of the air pollution level. Regarding to the meteorological conditions and the processes of the deposition of the pollution on the insulator surface, the distribution of the pollution stress of the insulators is determinable. The paper describes the operation of the measuring equipment and the use of the results for insulator dimensioning.
