THE SALT FOG TEST AND ITS USE IN INSULATOR SELECTION FOR POLLUTED LOCALITIES
(1876)
Abstract
After describing briefly the salt fog test, the authors
show, by means of comparisons between laboratory
results and results obtained in natural environments,
that the behaviour of insulators in salt fog is
very similar to their behaviour in representative types
of natural conditions. Having thus established that
the salt fog test is representative, the paper derives
certain fundamental rules relating to the behaviour of
insulators in salt fog as a function of their geometrical
and surface characteristics. The importance of
such rules is stressed in relation to the choice, on a
quantitative basis, of insulators for areas with different
degrees of pollution and suggestions are made as
to the criteria and methods to adopt for classifying
such areas.
