According to different requirements, it can set and control parameters such as transformation ratio, alarm and communication through the buttons on the instrument panel;
It is suitable for occasions that need to detect current in high and low voltage power systems;
When the event recording (SOE) function can be selected, it also has extreme value recording and maximum demand recording.
