Gaussian PMU measurement noise has been assumed
for many power system applications, such as state estimation,
oscillatory modes monitoring, voltage stability analysis,
to cite a few. This letter proposes a simple yet effective approach to validate this assumption by using the stability property of a probability distribution and the concept of redundant measurement. Extensive results using field PMU data from WECC system reveal that the Gaussian assumption is questionable.
