Abstract

Failures of power transformers as most valuable transmission system resources can cause high financial damage. Therefore on-site transformer monitoring was introduced in order to steadily analyze the operating conditions. Additional online transmission of certain monitoring values to the power system control centre enables to continuously assess the transformers´ internal thermal status and further the admissible overloading duration under given circumstances. If the results are immediately being displayed within the used power system control surface, the operators are given useful support in decision making, especially in critical network situations.
