| Abstract | The design and optimization of Combined Rogowski coil (CBRC) for the Partial discharge (PD) detection is proposed. The designed CBRC have shown to resolve the limitation of traditional Rogowski coil and Printed circuit board Rogowski coil (PCBRC). The electrical parameters that affected the performance of coil were controlled by the geometric variables and optimized by multi-objective genetic algorithm to achieve the optimum design of coil. The CBRC has upper frequency (fh) of 219.67 MHz and mutual inductance (M) of 96.747 nH, while PCBRC has fh of 200.63 MHz and M of 29.215 nH. The experimental results showed that the CBRC was able to measure the simulated of PD signal which is in nanosecond and current magnitude range of milli ampere. Its output signal has achieved better signal integrity and was able to eliminate the oscillation of detected signal output. |
