“…The purpose of changing these levels includes reducing the voltage or increasing the voltage. This transformer or transformer works based on the principle of electromagnetic induction and can only work on alternating current (AC) [7]. Transformers (transformers) play a very important role in the distribution of electricity.…”

The problem of this research is to generate electrical energy in the power plant which is located far from the load center, so it requires a transmission line in order to be distributed to the public. The purpose of this research is to find out the ratio on the primary (20,000Volt) and secondary (400Volt) power transformers using off load tap changer, then observe, operate, and analyze the comparison of calculation results with the Transformer Turn Ratio (TTR) tool. The proposed method is an analysis of the condition of the transformer in a state of extinguishing to find out the condition of the transformer's entangler. The comparison results that have been done can be known at a voltage of 40VAC, obtained the results of testing the TTR measuring instrument when it exceeds the tolerance limit of 0.5% then the measurement results on one of the coils undergo a change in ratio. Suggestions that transformers are routinely checked, because if ignored potentially unbalance voltage on one of the coils and it will result in loss of voltage.

The transmission line of electrical energy generated by the power plant is usually located far from the load center to be distributed to the community. The substation is part of a distribution transmission line that acts as a control center and consists of a collection of extra high voltage equipment. Routine maintenance of the power transformer as the main equipment of the substation must be scheduled so that its performance remains reliable. The proposed method of this research is to analyze the condition of the transformer through testing when it is off, to the calculation of the transformer ratio to determine the condition of the transformer windings using the calculation of the formula and measurement of the Raytech Transformer Turn Ration measuring instrument. In this research, the Raytech Transformer Turn Ratio measurement tool is used to determine the ratio of the winding input voltage of 20,000 volts and the output voltage of 400 volts on the power transformer. At a voltage of 40VAC, from the results of the comparisons that have been made, it can be seen that the test results of the Raytech Transformer Turn Ratio measuring instrument, if it crosses the 0.5% tolerance limit, the measurement results on one of the coils change the ratio. If the transformer is not regularly checked, the impact will result in unbalance of voltage on one of the coils. And one of the coils in phase will expand and cause a loss of voltage.
