Use of sensor networking technology to build a power transformer monitoring system

Abstract

The paper discusses the technology of designing a monitoring system for power transformers and power supply devices, based on the use of sensor networks, describes the creation of a Bayesian network to predict the probability of failure. Conditions for achieving the maximum diagnostic efficiency with the required accuracy are formulated. A diagnostic system is proposed that allows assessing the influence of each parameter on the accuracy of predicting failures. Using the method of expert assessments, the possibility to calculate the probabilities of failures with a lack of information is shown.
