Instrument Current Transformer Electric Combined Instrument Transformer/ Sensor FLPIT
1 .Introduction:
CY-EITDZI-36W type current and voltage combined transformer using plug-in type, independent pillar installation design. It suitable for outdoor pole-mounted installation. And can provide three-phase voltage and three-phase current signals for the grid overhead lines.
2. Features:
(1) The CT VT set can collect three-phase voltage and three-phase current signal, while the power
supply VT can provide power to the secondary terminal equipment;
(2) Its main body uses independent pillar design, suitable for the column installation of overhead
line;
(3) It is without iron core and can avoid magnetic saturation and ferroresonance issues, with
features of wide dynamic range and wide frequency response range;
(4) High measurement accuracy, use twisted-pair shielded cable for signal transmission, has a
strong anti-interference ability;
(5) Small size, light weight, low power consumption, energy-saving environmental products.
