| Abstract: | An overvoltage monitoring system based on Rogowski coil was proposed,in which the current signal flowing through the tap of transformer bushing was measured by the coil and was subsequently processed and recovered into overvoltage signal.Consequently,a Rogowski coil meeting the measurement requirements,a third-order integral circuit,and a trigger circuit were designed,and an acquisition and process program was coded based on LABVIEW language for the system.The results show that the proposed system can accurately record the overvoltage waveforms of power grid and satisfy the requirements for monitoring power grid overvoltage. |
| Keywords: | Rogowski coil high-voltage power grid overvoltage on-line monitoring system |
