what is differance between dirty earthing and clean
earthing and their applications
Answer Posted / eqbal_asif123
Basically earthing is of two types treated and untreated.In
case of untreated the electrode is not provided with any
external charcoal water mixture it is also called as dirty
earth.Where as in case of treated we provide water charcoal
powder mixture externally and in that case it is called
clean earth.Resistivity of treated electrode is lesser than
untreated one.so for equipment and safety earthing we go
for treated electrode.
