Application of the main transformer insulation oil monitoring system on line

摘要

It is one of the key factors of the electric power system safety that the insulation state of transformer is good or not .There are some shortcomings in oil chomaticity analyze which is usually done in laboratory. It brings up a method which keeps monitoring the dissolved gas chomaticity analyzing in transformer oil. It has the ability to know the condition to every moment. It expounds the necessity and the effect of chomaticity analyze monitoring system on line, and the basic request ,assessing method as well. It points up that the formal gas chomaticity analyze sooner or later would be replaced by a multi-functional dissolved gas which is in oil monitoring system on line as well as intellectual diagnosis device.
