Patent number: 10700542Abstract: A method of controlling the connection of a multiple phase power source to a plurality of capacitors. The method including, for each phase of the power source, determining a first voltage using a first voltage divider, the first voltage divider having a first high voltage resistor and a first low voltage resistor, wherein the first voltage is equal to a voltage across the first low voltage resistor. The method further including, for each phase of the power source, determining a second voltage across using a second voltage divider, the second voltage divider having a second high voltage resistor and a second low voltage resistor, wherein the second voltage is equal to a voltage across the second low voltage resistor. The method further including, for each phase of the power source, generating a close signal when the difference between the first voltage and the second voltage is approximately zero.Type: GrantFiled: June 27, 2017Date of Patent: June 30, 2020Assignee: Hubbell IncorporatedInventors: Joseph Gerovac, Robert A. Traska

Patent number: 9698600Abstract: Systems and methods for connecting a power source to switched capacitors are provided. A method may be used in controlling the connection of a multiple phase power source to a plurality of capacitors. Each phase of the multiple phase power source is electrically connectable to at least one of the capacitors through a switching device. The method comprises, for each phase of the multiple phase power source, determining a first voltage of a power signal for the respective phase of the power source using a first voltage divider that is electrically connected to a first terminal of the switching device for the phase. The method further comprises determining a second voltage across a capacitor that is connected to a second terminal of the switching device for the phase. The second voltage is determined using a second voltage divider that is connected to the second terminal of the switching device.Type: GrantFiled: November 3, 2011Date of Patent: July 4, 2017Assignee: Hubbell IncorporatedInventors: Joseph Gerovac, Robert A.

Patent number: 6747234Abstract: A circuit interrupter including a housing having an internal cavity. The internal cavity includes a space at a first end thereof, and includes an internal wall extending from the space to a second end of the housing. A vacuum interrupter is disposed in the space. The vacuum interrupter has at least one movable contact for contacting at least one stationary contact. An operating rod extends through the cavity, and is operable to move the moveable contact. At least one baffle is fixed to the operating rod, and disposed in the cavity. In a preferred embodiment, at least one step is formed in the wall. The step separates a first internal wall section from a second internal wall section, and the first internal wall section is closer to the space than the second internal wall section.Type: GrantFiled: July 23, 2002Date of Patent: June 8, 2004Assignee: Maysteel LLCInventors: Robert A.
