Voltage-energized status identification of three-phase underground power cables via non-destructive magnetoresistive sensor
Identification of voltage-energized cables can potentially prevent deadly consequences such as electrocution and explosion. We find that the voltage-energized status can be identified by measuring the distribution pattern of magnetic flux density around the cable surface. The weak magnetic fields emitted from the charging current of the voltage-energized cable are measured by sensitive magnetoresistive sensors in high spatial resolution. The feasibility of this non-destructive platform was verified on a 22 kV three-phase underground power cable. The platform can improve situational awareness of serviceman dramatically.
