Design of Broadband Planar Spiral Antenna for Partial Discharge in Cable

Article Preview

Abstract:

The detection of partial discharge in power cables is an effective method to diagnosis early fault of XLPE cable . When partial discharge occurs, it emits abundant frequency component in ultra-high frequency (UHF) band, and broadband planar spiral antenna is an effective sensor to detect UHF partial discharge signals. High frequency electromagnetic simulation software Ansoft HFSS is used to simulate and analysis planar Equiangular spiral antenna and Archimedean spiral antenna. The simulation results show that the two kinds of antennas work effectively in 400 MHZ ~ 1 GHZ frequency band and are high sensitivity and superior performance. Because of with smaller size and larger gain, the Archimedean spiral antenna is used to detect UHF signals of partial discharge in XLPE cable.
