| 20110298475 | METHOD AND DEVICE FOR MONITORING A SHEATH VOLTAGE ARRESTER OF A CABLE SYSTEM - Method and device for monitoring the status of a sheath voltage arrester of a cable system, a verification signal being supplied to a measuring loop which comprises the sheath voltage arrester and a measurement signal which is subsequently produced in accordance with the frequency-dependent impedance of the sheath voltage arrester being measured at the measuring loop in order to establish the status of the sheath voltage arrester by evaluating the measurement signal. | 12-08-2011 |
| 20110291666 | DEVICE AND METHOD FOR DETERMINING PARTIAL DISCHARGES AT AN ELECTRICAL COMPONENT - The present invention relates to a method for determining partial discharges at an electrical component ( | 12-01-2011 |
| 20110204899 | METHOD OF CALIBRATING A PARTIAL DISCHARGE MEASURING DEVICE - This invention concerns a method and devices for calibrating a partial discharge measuring device and for locating faults on cables. In the method, calibration signals, which can include a band-limited white noise, are used with a periodically repeated signal course. By averaging over a predetermined period duration (T) of the calibration signal, it is possible, in the case of a partial discharge measurement, to recalibrate the measuring device continuously during the measurement, and additionally on cables to determine the fault location with great precision. | 08-25-2011 |
| 20110031980 | SYSTEM FOR MONITORING A TRANSFORMER - This invention concerns a system for monitoring a transformer which comprises multiple terminals. The system includes multiple measuring devices and a transformer monitoring device. Each measuring device is arranged adjacently to a terminal of the transformer. Each measuring device includes a housing, a processing unit, a terminal to connect the processing unit to a sensing means to sense an electrical magnitude at the terminal of the transformer, and a data transmission terminal to transmit data between the processing unit and the transformer monitoring device. The transformer monitoring device, which is connected to the multiple measuring devices, is designed to determine, from a combination of the data from the multiple measuring devices, a present state of the transformer. | 02-10-2011 |
| 20100066376 | METHOD FOR TESTING A PROTECTIVE DEVICE, A PROTECTIVE DEVICE, AND TEST DEVICE - A method for testing a protective device as well as a correspondingly configured protective device and test device are provided. | 03-18-2010 |
| 20090216479 | METHOD AND APPARATUS FOR TESTING A POWER ENGINEERING DEVICE - A method and an apparatus for testing a power engineering device, for example a high-power transformer, are provided. A test signal is applied to the power engineering device, and this test signal, starting from an initial value, rises steadily and monotonically to a predetermined final value (U | 08-27-2009 |
| 20090051374 | Method and Device for Determining the Humidity Content of An Insulation of A Transformer - A method and a device for determining a humidity content of an insulation of a transformer, the insulation having a liquid. At least one dielectric property of the insulation is measured, an uncorrected humidity content of the insulation and a conductivity of a liquid which is included in the insulation is derived from a model of the insulation, said model being chosen depending on the measured dielectric property of the insulation, and the humidity content of the insulation is corrected by means of the conductivity. | 02-26-2009 |
