Abstract :
Careful inspection/inspection needs to be done to ensure that the transformer is always in good condition. If necessary, the transformer must be turned off to perform the inspection. With regular and careful examination will be known the condition of the transformer at all times and the damage that will cost big can be avoided.The test results of transformer 1 GI mualafa This for polarization index IS in the ungood range that shows the IP value between 1-1,1 which means the transformer isolation prisoner is decreasing. Voltage ratio in the range 0.7%-1.6% indicates that the ratio of voltage is not good or need to be done change, and Bdv (Breakdown Voltage) measured Under The use of Standard Oil is 40kv/2, 5mm signifies oil should be replaced and done recondition,. For testing (DGA Dissolved gas Analysis) is still in the standard by which TDCG (Total Dissolved Combustable gas) is measured still within the operating standard range of 84ppm.
