In this webinar Farnoosh Rahmatian will discuss how voltage and current sensors are the eyes and ears of the electric power grid. Traditionally, each specific application/function is performed by a device connected to dedicated sensors (e.g., instrument transformers) with very specific performance characteristics. With the evolution of the grid, there is a need for significant instrumentation investment to “see and hear” the grid better. There are substantial economic advantages to having sensors that have the performance (better linearity and bandwidth) to feed a multitude of applications concurrently, and digitization is key in achieving that. Digital voltage and current (V/I) sensors, if planned and used properly, can support the measurement needs of the grid economically, and lead to a more resilient and efficient grid.
In this webinar, we look at some of the challenges and possibilities that digital V/I sensors offer, including: High-level overview of V&I sensing technologies, waveforms (point-on-wave) versus calculated quantities (e.g., phasors), measurement speed, sampling rate versus bandwidth, the need to observe faster phenomena in the evolving grid, measurement data sharing amongst applications and importance of time synchronization, and layered data management architecture for reliability and resiliency.
