Radioimaging for real-time tracking of high-voltage breakdown
| DWPI Title: Interferometric radioimager for facilitating real-time tracking of high-voltage breakdown e.g. corona, has array comprising three radio-frequency sensors, and each radio-frequency sensors for detecting radio-frequency signal resulting from high-voltage breakdown |
| Abstract: An interferometric radioimager provides real-time, high-fidelity radioimaging of high voltage breakdown (HVB) both internal and external to electrical components at sub-nanosecond and sub-millimeter resolution and has an ability to resolve multiple/spatially-extensive HVB simultaneously. Therefore, radioimaging can be used to screen for early life weakness/failure and enable non-destructive screening of defective electrical components. In particular, radioimaging can detect precursors to catastrophic HVB, allowing for early detection of weakness in critical electrical components. Radioimaging can also be used to track HVB and pinpoint defects in electrical components real time, including transformers, capacitors, cables, switches, and microelectronics. |
| Use: Interferometric radioimager for facilitating real-time tracking of high-voltage breakdown. Uses include but are not limited to corona, sparks, arcs and streamers. |
| Advantage: The radioimager provides real-time high-fidelity radioimaging of HVB internal and external to electrical components at sub-nanosecond and sub-millimeter resolution, and resolves multiple spatially-extensive HVB simultaneously in an effective manner. |
| Novelty: The radioimager has an array comprising three radio-frequency sensors, where each pair of sensors in the array is separated by baseline distance and each baseline is oriented differently with respect to cardinal directions for providing three separate angles to the radio-frequency source. Each radio-frequency sensors detect a radio-frequency signal resulting from high-voltage breakdown, where the detected radio-frequency signals are used to constitute a radioimage of the radio-frequency source. The radio-frequency source is provided with an electrical component, where the radio-frequency sensor comprises a D-dot electric field sensor. |
