Title: Method and device for stabilizing generated voltage of electrostatic high-voltage generator
Inventor: MIYAKE YOSHINOBU
IPC: H02N1/08
Filed: 1995-04-24
Abstract: PURPOSE: To provide a method and device for stabilizing the generated voltage of an electrostatic high-voltage generator for accurately stabilizing the generated voltage by controlling corona current without using a vacuum tube. CONSTITUTION: The voltage of a high-voltage part 14 is detected by a CV detector 16, the signal is converted to DC by a rectification circuit 18 and a smoothing circuit 20, and the detection signal is calibrated by a gain zero adjustment circuit 22. Then, the calibrated detection signal is compared with a preset voltage 32 and the difference is amplified by a differential amplifier 24 and a control voltage 34 is generated, and then the control voltage 34 and a level shift voltage 36 are added by an adder 26.  A high-voltage power supply 28 where a voltage signal generated by the adder 26 is inputted outputs a voltage 38 corresponding to the level of the voltage signal and adjusts the increase and decrease of a corona current 40 flowing from the high-voltage part 14 via a corona needle 30, thus suppressing the fluctuation of the generated voltage of the high-voltage part 14 and stabilizing the generated voltage.

Title: Detection method for degradation of coil in rotating machine
Inventor: OGURA SATOSHI
IPC: G01R31/06
Filed: 1996-04-22
Abstract: PROBLEM TO BE SOLVED: To provide a detection method in which the electric degradation state or the mechanical degradation state, of a coil housed in a slot inside a stator at a rotating machine, which cannot be measured from the outside in conventional methods is measured without affecting the insulation characteristic of the rotating machine even when an object to be measured is in a live conductor state.

When the coil 4 is damaged due to an electric discharge, the optical fiber 6 is damaged, and the degradation of the coil 4 is measured by making use of a drop in its light-signal transmission characteristic. A change in the light- signal transmission characteristic is detected by monitoring the ratio of the intensity of incident light to the intensity of outgoing light on the basis of the optical intensity of the incident light on the optical fiber 6 and on the basis of the intensity of the outgoing light passed through the optical fiber 6 stretched inside the slot 3.
