Patent number: 8427333Abstract: A lightning detection system is presented. The lightning detection system includes a plurality of sensing devices configured to generate sensor signals representative of one or more working state parameters of an object. The lightning detection system further includes a lightning signal processing subsystem configured to combine the sensor signals representative of the one or more working state parameters received from the plurality of sensing devices to generate a composite signal, extract noise signals from the composite signal, and compare the extracted noise signals with one or more lightning signal profiles to determine existence of lightning noise signals in the extracted noise signals, wherein the lightning noise signals are induced in the sensor signals in response to a lightning strike on the object.Type: GrantFiled: June 29, 2009Date of Patent: April 23, 2013Assignee: General Electric CompanyInventor: Sebastian Gerhard Maxim Kraemer

Patent number: 8137074Abstract: A glass-reinforced fiber or carbon-reinforced wind turbine blade having a suction side and a pressure side includes a tip portion adapted with an electric field control region disposed solely on or within the tip portion. The electric field control region is in electrical communication with or galvanically connected to an electric discharge conduction mechanism, wherein the electric field control region and the electric discharge conduction mechanism together operate to protect a wind turbine and its associated blade(s) from damage due to a lightning strike at the tip of the wind turbine blade(s) by controlling an electric field at the tip portion(s) caused by the lightning strike.Type: GrantFiled: August 21, 2008Date of Patent: March 20, 2012Assignee: General Electric CompanyInventors: Yaru Najem Mendez Hernandez, Bastina Lewke, Matthias Menzel, Wilhelm Feichter, Sebastian Gerhard Maxim Kraemer

Publication number: 20110052115Abstract: A fiber optic sensor system employs at least one light source that operates to generate light having one or more desired wavelengths. A first optical fiber based sensor transparent to a desired light wavelength operates to sense a magnetic field emitted from a predetermined electrical conductor or a current flowing through the electrical conductor. A temperature sensor that may be another optical fiber based sensor operates to sense an operating temperature associated with the first optical fiber based sensor in response to the light generated by the light source. Signal-processing electronics adjust the sensed current to substantially compensate for temperature induced errors associated with the sensed current in response to the measured operational temperature of the fiber optic sensor.Type: ApplicationFiled: August 27, 2009Publication date: March 3, 2011Applicant: GENERAL ELECTRIC COMPANYInventors: Boon Kwee Lee, Renato Guida, Juntao Wu, Sebastian Gerhard Maxim Kraemer, Sachin Narahari Dekate
