Monitoring of oil distribution transformer in laboratory conditions

Abstract

The paper discusses the issue of analyzing the amount of gas and water contained in transformer oil. Such diagnostics include tests and measurements to verify the insulating and cooling properties of the oil, from which it is possible to determine the degree of transformer degradation. The experimental measurement is mainly focused on the state of the quantity of gases and water on the oil distribution transformer and their mutual ratios using monitoring and off-line measurements. In conclusion, an example of the analysis of the mechanical strength of the winding in the oil container of the aforementioned distribution transformer is the monitoring method of tracking the cooling curves through optical sensors.
