Outline Dimension
Notes: When using the product at the place where is above 1000m of sea level, relative amendment should be made on insulation withstand voltage which according to standard GB/T 11022.
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.
