4.2 Function description of the voltage regulation
The TAPCON® serves to keep constant the output voltage of a transformer
with an on-load tap-changer.
The TAPCON® compares the transformer's measured voltage (Uactual) with a
defined reference voltage (Udesired). The difference between Uactual and Udesired
is the control deviation (dU).
The TAPCON® parameters can be optimally adjusted to the line voltage re-
sponse to achieve a balanced control response with a small number of tap-
change operations.
The following diagram shows an overview of voltage regulation.

4.3 Performance features
The TAPCON® is responsible for controlling tapped transformers.
Apart from control tasks, the TAPCON® provides additional functions such
as:
▪ Integrated monitoring functions:
– Undervoltage blocking and overvoltage blocking
– Overvoltage detection with high-speed return
▪ Compensation for voltage drops on the line (line drop compensation)
▪ Compensation for voltage fluctuations in the meshed grid (Z compensa-
tion)
▪ Digital inputs and outputs can be individually programmed on-site by the
customer
▪ Additional indicators using LEDs outside the display for freely selectable
functions
▪ Display of all measured values such as voltage, current, active power, ap-
parent power or reactive power, power factor (cosφ)
▪ Selection of 3 different desired values

4.4 Operating modes
The device can be operated in the following operating modes:
Auto mode (AUTO)
In auto mode, the voltage is automatically controlled in accordance with the
set parameters. You cannot change further device settings in auto mode.
There is no active management by a higher level control system in this oper-
ating mode.
Manual mode (MANUAL)
In manual mode, there is no automatic control. The motor-drive unit can be
controlled via the device's operating panel. You can change the device set-
tings.
Local mode (LOCAL)
There is no active management by a superordinate control system in this op-
erating mode.
Remote mode (REMOTE)
In remote mode, you can perform commands using an external control level.
In this case, manual operation of the , , and keys is dis-
abled.
