VT is equipment to convert high voltage into standard voltage as needed. The possible cause of using the different VT source is based on the position or location of the BBVT from the nearest outgoing supplier. This gives rise to differences in multiplication in the calculation of power and energy that the kWh meter performs. The difference in voltage that occurs makes the result of energy multiplication incompatible between incoming and outgoing. Conversely, that in the power and energy calculation system, the value of voltage, current, and power factor must come from the same supply. If this continues and the result of the difference increases, the deviation that occurs will also be greater so that the losses experienced will be even greater. Therefore, in this case it is necessary to return the VT supply from the incoming side with the outgoing side corresponding to its transformer supply so that from a deviation of 1.5% it can drop to 0.7% so that with this it can drop to 0.8% from the initial value. For this reason, there will be no difference in multiplication in the calculation of power and energy.} }
