Sensors for PMUs

2016
Instrument transformers (ITs) are key elements in any measurement system and, in particular, their role is fundamental in applications such as PMUs, where the requirements on the measurement uncertainty are very strict. The characteristics, in terms of accuracy, electrical insulation, and mechanical property, that must be fulfilled by ITs employed in ...

“Frequency” and the PMU standard

2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2021
The Phasor Measurement Unit (PMU) has revolutionized power system management by providing high-resolution, time-stamped, spatial, and temporal measurements of the state of power systems. However, the standards defining the measured quantities have ambiguities that cause uncertainty, irreproducibility, and loss of interoperability during periods of ...
