Improvement of earthing mode for high voltage cable on type HX_D1B locomotive

Application of fiber Brillouin sensing system in high-voltage cable detection;

The anicle analyses the failure cause and representative form of high-voltage cable, introduces the four-wire method to Check Fault of Power Cable and apply it to case study, the method has a high percentage of accuracy.

At present,off-line monitoring is still wildly used in XLPE high-voltage cable maintenance.

An experimental investigation on a solid in high voltage cable s oil-paper insulation produced under electric field;

This paper introduced the distributed temperature sensing based on fiber which is used to monitor the surface temperature of high voltage cable,and gave out the thermal circuit model to calculate the temperature of cable core by surface temperature,and analyzed the.

It automatically compensates the non-synchronization between the traction speed and corrugating speed by the movement of a corrugation carriage so that variation in corrugating pitch and wrong corugation are eliminated during the production of the metal sheath of HV cables.
