Page 12: Vt Ratio
Programming VT ratio This function allows the user to select the value of the VT ratio. Example: if the primary of the con- nected VT (voltage transformer) is of 20kV and the secondary is 100V, the VT ratio will correspond to 200 (obtained by carrying out the fol- lowing calculation: 20000/100). - Page 13 Programming If, for example, you select the value “15 min- utes”, the instrument calculates the demand value and updates the value every 15 minutes. See the diagram below.
