This paper introduces Artificial Neural Network (ANN) method for measuring voltage in the Optical Voltage Transducer (OVT) using one or more electric field sensors. In order to obtain an accurate voltage measurement with minimum number of sensors, first the locations of sensors are specified by quadrature method. Then the electric field intensity at these locations is provided to ANN for the calculation of applied voltages. Less number of sensors with no displacement required to obtain high accuracy is the most important advantage of this method. The numerical simulations demonstrate the effectiveness of this technique.
