Paper Abstract

Nonconventional instrument transformers based on intensity modulation of optical signals have been reported in the literature for more than 20 years. Recently described devices using passive bulk optical sensor elements include the electro-optical voltage transducer (EOVT) and magneto- optic current transducer (MOCT). These technologies offer substantial advantages over conventional instrument transformers in accuracy, optical isolation, bandwidth, environmental compatibility, weight and size. This paper describes design and manufacturing issues associated with the EOVT and the optical metering unit (OMU) recently introduced by ABB with field installation results presented for prototype units in the 345 kV and 420 kV voltage classes. The OMU incorporates an EOVT and MOCT to monitor the voltage and current on power transmission lines using a single free-standing device.
