The principles of electro-optic and magneto-optic sensors suitable for use in power-system applications are reviewed with particular attention to the properties of materials and components that limit the precision of such sensors. Data on a number of materials are collected and presented. For high-precision electro-optic sensors, it is recommended that crystals of point symmetry (bar 4)3m be used. For high-precision magneto-optic sensors, a lead glass with a low stress-optic coefficient is recommended. Choices for other components are also suggested. For both types of sensors, a precision of roughly plus or minus 1 percent over a 100 C temperature range should be attainable. To achieve a precision better than that, it will be necessary to use temperature compensation techniques, several of which are proposed and discussed.
