Transformer Management Models
Power transformers are one of the most critical components of power systems. The cost of such units and the consequences of unexpected failure has always been a concern for system operators. It is no wonder that monitoring devices such as Buchholz gas relay and winding temperature indicators have been used for many years. More recently, the availability of microprocessors, ruggedized for high voltage substation environment, had made it possible to monitor a large number of parameters. With large memory capability and communication facilities it is tempting to record all these data for future usage.
However experience has shown that the monitored values are of limited interest by themselves. They gain there value when compared with rated values and combined among themselves to generated more significant information. This is the purpose of transformer models provided with Hydran M2 and Intellix MO150. In the following pages, these models are described along with the benefit to the user the user.
