| 20100220418 | ALTERNATOR CIRCUIT-BREAKER WITH AN INSERTED RESISTANCE - An alternator disconnector circuit-breaker of the invention presents a resistance ( | 09-02-2010 |
| 20100220417 | COMPACT DISCONNECTOR CIRCUIT-BREAKER FOR AN ALTERNATOR - An alternator disconnector circuit-breaker of the invention presents a compact structure. The axes of opening/closure of the change-over first switch ( | 09-02-2010 |
| 20090230933 | HYBRID ON-LOAD TAP CHANGER AND A METHOD OF OPERATING THE SAME - A hybrid on-load tap changer, for use in high voltage alternating current power transmission, including a selector and a diverter having two legs defining respective current paths. Each leg includes a pair of opposed first and second semiconductor switches. The hybrid on-load tap changer also includes a controller configured to switch on one of the first or second semiconductor switches of a given leg at a predetermined point within the alternating current cycle so as to commutate off a desired semiconductor switch in the other leg. | 09-17-2009 |
| 20090139956 | Dielectric Insulation Gasket for a Vacuum Bottle - The gasket makes it possible for the apparatus, in particular the vacuum bottle, to be assembled and disassembled relatively easily and conveniently. It imparts high dielectric performance to the apparatus. The inside and the outside contact surfaces of the gasket are smooth, and, for example, each of them can be made up of two cylindrical portions ( | 06-04-2009 |
