GFECT-1PD2 MEDIUM VOLTAGE LOW-POWER CONSUMPTION SINGLE PHASE ELECTRONIC CURRENT TRANSFORMER
INTRODUCE
The GFECT-1PD2 series current sensor is a single-phase structure, cast with epoxy resin, fully enclosed insulation, safe and reliable. It is fully enclosed and insulated, safe and reliable, suitable for traditional switchgear and GIS switchgear. It is suitable for current measurement (metering) and protection in AC 50/60Hz lines with the highest voltage of 40.5kV and below.
In order to ensure good anti-interference ability, the secondary signal output terminal and signal line of the GFECT-1PD2 series current sensor have been specially shielded. Customized interface solutions can be provided according to the specific requirements of customers.
All of our GFUVE electronic current transformers are strictly comply IEC60044-8, IEC 61869-6, ANSI/IEEE C57.13, GB/T 20840.6, GB/T 20840.8, IEC/EN61010-2-032, IEC/EN 61010-2-031.
