Real time web based condition monitoring system for power transformers - Case study

The need for improved performance of power systems in terms of reliability and higher productivity has necessitated more and more application of condition monitoring techniques, which can provide early warning of potential failure with the opportunity of organizing avoidance strategies to minimize loss of time and unexpected costs. Periodic condition monitoring tests have limitations such as continuous availability of data and will lead to reactive maintenance. Any event happening between the monitoring intervals is lost and by the time it is noticed the severity of fault might have increased manifolds. To overcome this continuous monitoring solutions are gaining demand. Many stand alone solutions are available in the market for local SCADA applications. Development of a versatile real time web based monitoring system (DAKSHITATM), which can take simultaneous inputs from multiple sensors, equipments and sites, are explained in this paper.
