Abstract
We demonstrate three different types of secondary interfaces with optical current and voltage sensors: digital, low-energy analog, and high-energy analog. We compare the merits and limitations of each type of output. In all cases the digital output is superior to the analog due to inaccuracies in the converters and amplifier limits. In some cases the digital optical output has accuracies equivalent to a transfer standard
