Abstract :
In this final project research aims to evaluate the insulation performance on the current transformer unit of 1 substation transformer of the Cikupa stem using tangent delta. The test uses three ways, GST-GND, UST-R and GSTguard. Based on the results of the tangent delta using the test equipment Delta Magger 4000 in the current R phase transformer is 0.76%, in the S phase is 0.80% and at the T phase is 0.82%. From that data then the isolation on the current transformer is still worth operating as it still meets the standards. The standard used is where when the < 1% The current transformer is still said to be eligible to operate and if > 1% then the current transformer is in bad condition and will be doing repairs or replacement of the current transformer
