Electric Heating Cable Fault Testing System Based on Wavelet Packet and RBF Neural Network
A new method for testing of the electric heating cable fault was proposed,which was based on the wavelet packet and RBF (radial basis function) neural network. The principle used for testing the short-circuit fault of the electric heating cable was described. The flow chart of the detecting system was given. Experimental results showed that the method, which combined the wavelet packet and RBF neural network, could be used to improve the effectiveness of locating the electric heating cable fault.
A Device for Fault Testing of the Underground Electric Heating Cable
This paper introduced a new type of fault testing device for underground electric heating cable. A new design concept was adopted and intelligent control techniques were used in the trouble-shooting testing system for buried electric cable. The testing principles of the short-circuit fault point and the breaking point were discussed. The performance and functions of the device were described.
Development of the Cable Fault Detection
This paper reviewed the trditional methods for the detection of the cable fault,analyzed their shortages,and introduced some new methods for the detection.the trend of the development of cable fault detection was discussed as well.
