Scan option:
Can be used in Manual or Automatic modes. This option provides uniform utilization of the capacitor groups,
which is carried out by transient free switching between engaged and non-engaged capacitor groups every few
seconds in FIFO rotating sequence (First In First Out). Prevents overloading and overheating of the capacitors
and inductors. |

Measurement System |
Simultaneous measurement of the following sections:
Mains (total of load and capacitor system)
Load
Capacitors (system)
Combination of Mains, Load and Capacitors.
For example, if reactive energy parameter is selected, the user can see the kVAr consumption by the Load, the
connected kVAr by the Capacitor System and the result on the Mains.Calculation method:
True RMS measurements (up to 63rd harmonics)
Based on FFT algorithm which is carried out cycle by cycle (128 samples per cycle)Measured parameters:
