| Abstract: | Setting up a current isolation transformer in the current loop of the three-phase energy meter testing device can make the three-phase energy meter not only realize the potential check such as not off the hook with multi-epitopes but also verify the inline three-phase energy meter.It is a new calibration device of electric energy meter which released in recent years.The paper investigated the current isolation CT testing methods used for this type of device and proposed two methods:Standard power transforme... |
