Wavelet analysis based condition monitoring of fuelling machine grab cables

The increased challenges to reduce operating costs, enhance the availability of the generating and transmission equipment and improve the supply of power and service to customers, have produced a need for condition monitoring of power system equipment. The fuelling machine grab cables are subjected to repeated bending around a series of pulleys that induce a twist in the cables. The twisting of the cables ultimately results in the failure of the cables. In this paper, a new method, WACM, is proposed. Wavelet analysis is used to detect the twisting degree. The calculation results show that this method is superior to DLCM.
