  • Page 84: Bandwidth

    7 Functions and settings 7.3.7 Bandwidth The bandwidth is the permitted deviation of the measured voltage (V ) from Actual the selected desired value. If the measured voltage is inside the bandwidth, then no control commands are issued to the on-load tap-changer. If the measured voltage deviates from the specified bandwidth, a tap-change command occurs after the set delay time T1.
  • Page 85 7 Functions and settings 7.3.7.1 Visual display The deviation from the set bandwidth is shown visually in the device display. The measured voltage mark (V ) shows whether the measured voltage is actual above, within or below the set bandwidth. Progress of delay time T1 is indi- cated by the gradual filling of the time bar in the device display.
  • Page 86 7 Functions and settings 7.3.7.2 Determining bandwidth In order to be able to set the value correctly, the transformer's step voltage and nominal voltage must be known.

  • Page 88: Setting Delay Time T1

    7 Functions and settings 7.3.8 Setting delay time T1 Delay time T1 delays the issuing of a tap-change command for a defined pe- riod. This function prevents unnecessary tap-change operations if the toler- ance bandwidth is exited. If the current measured voltage exits the bandwidth, delay time T1 starts. This is shown in the display by the time bar filling and the remaining time being in- dicated.
