The Value of Information Obtained Through Transformer Monitoring System

Transformer reliability and availability are keys to a profitable process of power generation and transmission. On-line supervision of transformers improves their reliability, positively influencing correct and safe functioning of the whole power system. To achieve the desired transformer availability, the user should have information about the transformer state and operating conditions. Especially, he should have information about incipient faults before they escalate into failures. A transformer monitoring system with ability to supervise all the significant transformer parameters is the proper way to obtain valuable information, and on the basis of trustworthy information to achieve the desired reliability and availability, personnel and environment safety. Diagnostics combined with monitoring information results in better diagnostic decisions and recommendations. Information obtained through monitoring system enables also transformer producers to improve and optimize the design and the production process on the basis of real-time operating parameters, what results in better features of transformers. The insurance companies scale insurance premium for equipment insurance according to the state of equipment, frequency of failures and other information based on risk evaluation. The monitoring system information could provide data for evaluation of the transformer state and prediction of possible failures, what is important for insurance.
