摘要： A method for detecting events associated with partial discharges (PDs) in high voltage equipment and installations diagnoses insulation conditions in real time by using PD signal noise discrimination by the parallel use of multiprocessors, which are additionally used for the discrimination, in real time, of different PD sources located in a single position or in different positions. In order to identify the various PD sources, three-dimensional clusters are formed using the coordinates of three parameters characteristic of each pulse: the parameter associated with the front time of the impulse, the parameter associated with the tail time and the parameter associated with the pulse frequency. The diagnostic method can be performed with grid voltage or independent generators as a voltage source, and the invention particularly relates to a novel voltage source designed therefor. A system for the implementation of the method captures PDs, and performs the necessary analysis and measurement.

摘要： A method for assessing insulation deterioration in a live underground power cable may include, in one embodiment, attaching a coupling device to a live underground power cable and using the coupling device to couple a test signal onto the power cable. The power cable may carry a normal AC power signal at a first frequency, while the test signal may have a second frequency different from the first frequency. The test signal may be detected after it has traveled a distance along the power cable. It may then be analyzed to determine a change in velocity and/or attenuation of the test signal as a function of the normal AC power signal. The severity of water trees in the power cable may be inferred based on the magnitude of the change.

摘要： A partial discharge detection device for detecting and measuring partial discharges in electric systems or components, which delivers signals having a form much resembling that of the radiated pulse, for improved identification and analysis. The device is of small size, totally insulated and self-powered, and allows measurements to be performed with the highest safety with no need for direct connection, thereby allowing operators to stand at a distance and avoid any system shutdown while making measurements. Furthermore, it can also detect and deliver the sync signal, which is obtained by picking up the supply voltage of the discharge generating components.

摘要： A method and device for monitoring partial discharges in high voltage electrical or power systems is provided. A low trigger level and a high trigger level electrical pulse amplitude levels are defined. At least one phase of the electrical system is monitored for an occurrence of a pulse within a defined minor time frame. A peak amplitude of a pulse occurring in the electrical system within the minor time frame is detected. It is determined if the detected peak amplitude of the pulse exceeds the lower and higher trigger levels. A pulse number is assigned to the pulse if the peak amplitude of the pulse exceeds the trigger levels. The pulse is captured if the pulse number associated with the pulse is less than a predetermined pulse number threshold in the minor time frame. The captured pulses are stored in a memory.
