摘要：
This paper introduces an analytical tool for remote monitoring of on-load power transformers. Dissolved Gas Analysis, which is the most recommended and accurate condition monitoring technique suitable for remote condition monitoring, is selected as the analytical method in this tool. Proposed setup supports remote condition monitoring by drawing an oil sample to the gas extraction unit where the dissolved gasses are extracted and sent to the gas analyzer without deenergizing the power transformers. Non-Dispersive InfraRed technology is used to measure the concentration of extracted gasses and the results are communicated to the control center using wireless technology. CO2/CO ratio and Hydrocarbon analysis based on Duval's triangle are used to interpret the results for diagnostic purposes. Results obtained using the proposed tool have been validated against a commercial dissolved gas analyzer in order to certify the proper functioning of the tool. This tool, once fully implemented, can be used to monitor the condition of on-load power transformers from a remote location.
