| 20100292863 | CONTROL SYSTEM AND A METHOD OF CONTROLLING A TCSC IN AN ELECTRICAL TRANSMISSION NETWORK, IN PARTICULAR BY AN APPROACH USING SLIDING MODES - A system and method of controlling a TCSC disposed on a high voltage line of an electrical transmission network. The system comprises: (a) a voltage measuring module; (b) a current measuring module; (c) a regulator, working in accordance with a non-linear control law to receive on its input the output signals from the two modules for measuring voltage and current, and a reference voltage corresponding to the fundamental of the voltage which is to obtained across the TCSC; (d) a module for extracting the control angle in accordance with an extraction algorithm; and (e) a module for controlling the thyristors (T | 11-18-2010 |

| 20100102035 | POWER LINE CURRENT INTERRUPTER HAVING A VACUUM SWITCH CHAMBER - This interrupter device includes a parallel branch ( | 04-29-2010 |
| 20100089732 | ELECTRICAL SWITCH APPARATUS HAVING TWO INTERRUPTERS, SUCH AS A BUSBAR DISCONNECTOR AND A GROUNDING DISCONNECTOR, AND INCLUDING COMMON ACTUATOR MEANS FOR THE MOVABLE CONTACTS OF THE INTERRUPTERS - A switch apparatus comprising two interrupters, such as a busbar disconnector and a grounding disconnector. Common actuator means are provided for the movable contacts of the interrupters, for permitting one of the interrupters to be opened while holding the other interrupter closed, and vice versa, which enables the strokes performed by the movable contacts to be crossed. | 04-15-2010 |
