Title: Detection method of abnormality of corrosion-resistant layer of power cable
Inventor: FUJIEDA TAKASHI
IPC: H02G9/00
Filed: 1987-12-25
Abstract: PURPOSE:To establish a method for continuously detecting and monitoring the presence or the absence of defects of a corrosion-resistant layer by attaching optical voltage dividers using optical voltage sensors to the insulated connection part and the non-grounded normal connection part of a single core power cable. CONSTITUTION:An optical voltage divider 5 which can endure the sheath voltage induced by a core surge voltage is attached to an insulated connection part 2 in each phase of a single core power cable 1. The optical signal output of the optical voltage divider 5 is converted to a voltage value by a transducer 6 and is sent to a central unit 7 and is compared with a power value obtained by using a preliminarily inputted power for normalcy as a data base. If a defect exists in the corrosion-resistant layer at a point X1 of a power line 10 shown in a figure (a), the voltage in a phase A of the insulated connection part 11 is lower than that for normalcy as shown by a solid line in the figure though it must rise in proportion to the load current as shown by a broken line in a figure (b). Consequently, the voltage of the connection part 11 is always monitored to decide the presence of the defect in the corrosion-resistant layer.

The deviation (e) of actual flow rate and set flow rate SV is found and a second arithmetic means 33 performs a PID control calculation based on this deviation (e). A third arithmetic means 3 adds this arithmetic result MVPID and the arithmetic result MVFF with the first arithmetic means 30 and obtains a first correction valve opening MVO. A fifth arithmetic means 36 adds the first correction valve opening MVO and the amplified flow rate calculated by the second arithmetic means 33. A sixth arithmetic means 37 performs the calculation for compensating phase deviation and useless time from this result and calculates a second correction valve opening MV.
