Abstract
A power cable measurement device is provided, which may include a casing, a plurality current sensing modules and a plurality of voltage sensing modules. The casing may be used to envelope a three-phase three-wire power cable. The voltage sensing modules and the current sensing modules may be disposed on the casing and spaced at regular intervals; any two adjacent current sensing modules may be divided by one voltage sensing module. The power cable measurement device can accurately estimate the electricity information of the three-phase three-wire power cable according to a characteristic curve database constructed by pre-measurement, the induced voltages of the voltage sensing modules and the induced voltages of the current sensing modules.
