摘要：
The safe operation and the extension of the remained life of power transformers have been dominant objectives during the last years. An accurate assessment of the remained fife could be an important instrument for the safety of the power transformers in operation. The paper presents the structure and the using mode for an integrated monitoring-diagnosis system (SMD) for power transformers. The monitoring-diagnosis system allows on-line analysis on a desktop application, a web application and off-line analysis for determining the transformer condition, by means of which there are surveyed: Cooling system condition; OLTC condition; Bushing condition; Insulation system condition; Partial discharge evolution; Transformer switching in/switching off: Exceeding of monitored parameter limits; Estimation of remained life. SMD allows determining accurately the transformer condition and the monitored parameters evolution in time, avoiding the appearance of incidents and failures and specifying certain type of maintenance.
