Material
The Configuration of Current Transformer
External current transformer works as protection, with the transformation ratio 50/5600/5 and the standard configuration is 2pcs. The maximum quantity is 6pcs (one group is for measurement, the other group is for protection). Once the requirement of measuring winding precision is above level 0.5, the transformation ratio is 200/5,300/5,400/5,600/5.
Operating Power Supply
The operating supply is from the AC/DC low-voltage 220V (110V) provided by users or from the secondary voltage of AC 220V (110V) output by the voltage transformer (external) connected to the 10kV overhead line. For the purpose of convenient installation, the outdoor type voltage transformer with fuse protector is recommended.
Application Conditions
1 Ambient Temperature: -45℃~+40℃
2 Range of Daily Temperature: ≤25℃
3 Wind Speed: ≤35m/s
4 Elevation: ≤1000m
5 Seismic Intensity: ≤8 degrees
6 Ambient Humidity: Monthly value of relative humidity ≤90%, daily average value of relative humidity ≤95%
7 Thickness of Ice: ≤20mm
8 Application Site: No danger of inflammability and explosion, chemical corrosion or violent vibration.
