Abstract

The main effect factors and relevant solutions in testing dielectric loss of substation electric equipments was instructed

and two kinds of instruments frequently used for dielectric loss measuremeat were compared.The measuremeat methods for dielectric loss of main electric equipments in transformer substation were discussed.According to dielectric loss value

insulation status of electric equipments was analyzed and summarized with examples.It is helpful to find insulation faults quickly and exactly in fieldwork

and the electric equipments can be overhauled or replaced in time

hence the electric power system be ensured to run safely and stably.
