Study on calibration of impulse current measuring system

The calibration of the impulse current measurement system has been clearly stipulated in the standard GB/T 16927.4-2014, With the implementation of GB/T 16927.4-2014. In order to promote the standardization of the calibration system, this paper analyzes the impulse current measurement system architecture, Analysis of the impulse current measurement system scale factor calibration methods and the uncertainty calculation of time-parameter measurements. Then, each test example was executed. The uncertainty of under calibration impulse current measurement system was evaluation, For the implementation of standard provides the beneficial practice and guidance.
