Abstract：
 The apparatus thereof comprises: a flexible Rogowski coil used for making the pulse current measurement for the current carrying conductor under test; a integrator used for making integration restore for the signals outputted from the flexible Rogowski coil in order to get the analog signals which is proportional with the derivate of the pulse current under test; a data sampling module used for making analog modulation for the analog signal outputted from the integrator in order to get discrete sampling signals; a A/D converter used for converting the analog signals to the digital signals; a CPU used for processing the data outputted from the A/D converter in order to get the pulse signal under test; a radio communication module used for making communication; a GPS module used for demarcating the clock of the CPU.
