Hassan Monsef; Taher Ghomian

Volume 42, Issue 7 , January 2009, , Pages 913-922

https://doi.org/10.22059/jac.2013.7811

Abstract
  There are fewer problems encountered with optical voltage transducers in comparison with their inductive and capacitive counterparts. Although capacitive and inductive transformers are used vastly for the purpose of measurement and protection in the networks, they cause problems such as core saturation ...  Read More

اندازه‌گیری دقیق ولتاژ الکتریکی در مبدل ولتاژ نوری با استفاده از شبکه‌های عصبی

Hassan Monsef; Taher Ghomian

Volume 41, Issue 5 , December 2007, , Pages 643-651

https://doi.org/10.22059/jac.2013.7876

Abstract
  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 ...  Read More
