what is derating factor in Cable ? how we minimise this?
Answer Posted / viral
Due to partial discharges in cable it can't be utilized to
it's rated capacity.
As current flowing to charge cable capacitance is extra
burden on that which will make it to carry less current for
load.
To reduce this good insulation material should be use.
