This article presents research on novel optical voltage sensor designs, including a transmission-type sensor using a photonic crystal fiber quarter-wave plate and a reflection-type sensor without a quarter-wave plate for high-voltage applications, along with their. Instead, it can be integrated into primary high-voltage equipment such as circuit breakers – this results in substantial savings in space and i stallation costs. Another important aspect of the new technology is its ability to communicate digitally, via an optical process bus.
