Abstract

The process distribution electrical energy of power transformer is really important, especially, 60 MVA of power transformer that use to decrease 150 Kv high voltage into 20 Kv middle voltage. Thefefore, it is necessary to provide pacification of transformer security that can protect transformer from variousdisturbance. Besides that, the pacification also can restrict the disturbance current mat can, give endanger for human and grounding system. The problem happend about security of grounding system are “how keep the establishment value of available grounding ristance ? “and to know “is the grounding resistance on the power transformer follow or not the certainly grounding resistance that should order 5 ohm. from the problem above, it means that we can do the measurement, calculation and comparison between measurement and calculation from 60 MVA power transformer of grounding system, based on data that the writer got, the result of measurement was 0,2 ohm and the result of calculation was 0,24 ohm. Therefore, the comparison between measurement and calculation was similarity. In brief, the writer conclude that the value grounding system resistance of 60 mva power transformer already fulfill certainly. The writer suggest that the staff should make schedule for carryiing out the grounding system regularly.
