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 and improper transient responses which decrease the accuracy of measurement and efficiency of the protection schemes. As a result, OPTICAL VOLTAGE TRANSDUCERs are considered as proper candidates for replacing the conventional inductive and capacitive transformers. Lighter weight, smaller size, larger dynamic range, wider bandwidth, insensitivity to electromagnetic interference, stability over temperature change, absence of iron core saturation, low maintenance and replacement cost, etc. are some of the advantages of OPTICAL VOLTAGE TRANSDUCERs over inductive and capacitive transformers. In this paper, the MODIFIED ADAPTIVE METHOD is introduced in order to measure the integral of ELECTRIC FIELD with minimum number of sensors. Using this algorithm makes the effects of other fields minimum. One more advantage of this method is the possibility of improving the accuracy of the measurement by using a CORRECTION FACTOR. The CORRECTION FACTOR is determined by considering the level of accuracy, environmental conditions and the number of sensors. Simulation results show the great validity and effectiveness of this method over a wide range of variations.
