Title: Detecting device for cylindrical object
Inventor: KAIHO SATORU
IPC: G01N21/956
Filed: 1981-07-30
Abstract: PURPOSE:To automatically detect a cylindrical object without contacting with the object at a high speed by forming an image of the inside of the cylindrical object on a photoelectric conversion part through a wide angle lens and comparing the pattern of its electric signal with a standard pattern. CONSTITUTION:An image of the inside of a cylindrical object 12 to be detected is formed on a photoelectric conversion part 6 through a wide angle lens 5. A control signal from an operating part 18 is supplied to the photoelectric conversion part through a scanning part 9 and pattern information is generated from the photoelectric conversion part 6. The information is converted into a series signal by a parallel to series converting part 7 and stored in a storing part 24 through an amplifier 8 and a receiving part 23. The stored pattern information is read out by the operating part 18 and compared with a standard pattern from an ROM19. If the operated result is included in the tolerance limits a correct signal is sent through an interface part 17 and, when the result exceeds the tolerance limits, an error signal is sent 30. Consequently the pattern is automatically detected without contacting with the object at a high speed.

Title: Protective relay unit for transformer
Inventor: USUI MASAJI
IPC: H02H7/045
Filed: 1990-05-09
Abstract: PURPOSE:To make it possible to detect exciting surge current even when a CT is saturated by detecting second higher harmonic component of current prior to triangular connection of a CT on the side of star winding of a transformer. CONSTITUTION:Currents flowing through high voltage side buses 1a, 1b, 1c of a transformer are detected through metering current transformers 6a, 6b, 6c and fed through second higher harmonic content detecting circuits 23-25 to ratio differential relays 8, 9, 10. In the case the primary current contains second higher harmonic such as exciting surge current, the content of second higher harmonic in the secondary current of CT increases as compared with the primary side thereof. Since the relation is maintained untill the CT is connected in triangular, degradation of sensitivity for detecting the exciting surge current due to saturation of CT ca be prevented by detecting the content of secondary higher harmonic in the star current prior to triangular connection of the CT.
