S&T Project Number 19219 Final Report: Feasibility of Utilizing Optical Instrument Transformers

Conventional instrument transformers constructed with copper and iron are an integral component of the modern power grid. These conventional devices have well known accuracy and safety drawbacks. These drawbacks are accounted for in system design. Optical instrument transformers utilizing the interaction of light with electromagnetic fields are an alternative to conventional instrument transformers. However, these optical instrument transformers are not a one-to-one replacement for conventional instrument transformers. The optical versions are more complex but can provide real benefits. This report examines the properties of optical instrument transformers, reviews the use of one in a lab environment, and discusses the use of them in the power grid.
