Transmission & Distribution
PI Vision has been very useful and efficient to OSIsoft PI System users. To very specific applications, PI Custom Symbols provides this flexibility and added functionality to better Insights not just raw data. Tenaga Nasional Berhad (TNB) has implemented the Duval's Triangle in their Power Transformer monitoring with collaboration from their System Integrator - Calibr8 Systems. TNB gathers data from their online DGA devices and via customized loggers to automatically plot the data points in the Duval's triangle in real time. Thus providing real time interpretations and diagnostics of the Health of the Power Transformer. This is very helpful as they monitor around 500 Power Transformers, which they put into analytics such as Rate of Change to better see the trending and diagnostics of the DGA per Oil Sampling. TNB GSE went a step further by implementing the newly released Duval's Pentagon for more accuracy in their Transformer Health Insights. More and more data is being put into the PI System.
