| 20080228416 | Indirect rotor resistance estimation system and method - Indirect rotor resistance estimation for an AC induction motor is achieved by successively stepping the quadrature command to zero and the direct current command to a predetermined value causing the quadrature stator voltage to decay as a representation of rotor current decay; defining, in response to the decaying stator voltage reaching two spaced thresholds, a voltage/time difference, and retrieving from a storage device the rotor resistance associated with the voltage/time difference. | 09-18-2008 |
| 20090189553 | Method and system for multiphase current sensing - A multiphase current sensing method wherein the sum of the phase currents is zero including: sensing a.c. and/or d.c. currents in first and second phases; sensing a.c. current in a predetermined a.c. frequency range in a third phase; and combining the current sensed in the first and third phases and the second and third phases and determining a gain correction factor to be applied to the currents sensed in the first and second phases. | 07-30-2009 |

| 20110030993 | Corona shield and composite insulator with corona shield - A composite insulator comprises a rod with an insulating jacket and ribs and at least one end fitting and at least one corona shield. The latter is integrally manufactured from plastic material. It is configured to be coaxially disposed on the composite insulator at the transition from the rod to the end fitting. The corona shield forms a cavity, which is open towards the inside and which can be filled with sealant compound through at least one filling channel and which comprises a closing cuff in axial direction on both sides for sealing the cavity. The diameter of the rod side closing cuff is adapted to the diameter of the insulating jacket, and the diameter of the fitting side closing cuff is adapted to the diameter of the end fitting. The filling channel leads to the cavity from the outside. | 02-10-2011 |
