Title: Photoelectric current transformer and protection relay system using it
Inventor: ICHINOSE YUJI
IPC: G01R15/24
Filed: 2000-07-18
Abstract: PROBLEM TO BE SOLVED: To produce the digital output signals of a photo-CT(photoelectric current transformer) without using an accurate A-to-D converter and enhance the reliability of a protection relay system. SOLUTION: The angle of polarization by the Faraday effect brought about in a sensor fiber wrapped around a conductor is detected as variation in intensity by photodetectors 120 and 130, and the signal difference obtained from the output of amplifiers (123 and 133) or (124 and 134) with a high or low amplication factor according to the high or low value thereof is digitized in a conversion portions (A/D2) or (A/D3). Thus, the individual conversion portions (A/D2) and (A/D3) do not require an especially large number of bits. In addition, sampling is performed at a frequency 360 or higher than the frequency of the photo-CT system current and any delay arising from transmission is corrected at a digital relay processing portion, so that protection relay processing can be performed at a current with less phase delay.  The value of the current of the photo-CT and presence/absence of a sensor trouble are transmitted as transmission data to a digital relay, so that malfunction of the digital relay due to malfunction of the photo-CT is prevented.
