Adopting the principle of LPCT low-power coil, it can directly output standard small signal without secondary conversion, and directly input secondary equipment through A/D conversion;
The magnetic core has high permeability and low temperature drift. In the temperature range of -40℃～+70℃, especially at -40℃, the variation of the error meets the standard requirements
Using low temperature drift resistance, it can work for a long time under 4 times the current, and work for a short time under the condition of 10 times overload;
At 30 times the current, that is, single-phase 600A, the zero-sequence output can work for a long time;
The secondary signal output adopts shielded cable to prevent interference.
