Setting the desired voltage level 1
The setting of the desired voltage level refers either to the
secondary or to the primary voltage side of the voltage
transformer connected to the TAPCON® 230 VC.
‘V’ stands for the secondary voltage which is indicated in
Volt. ‘kV’ stands for the primary voltage which is indicated in
Kilovolt. Press the SET and
function keys to set
the desired voltage level.

Setting the bandwidth
Set the bandwidth from ± 0.5 % to ± 9% in steps of 0.1 %
by pressing the SET and
function keys. The trans-
former’s step voltage must be known to ensure proper
setting of this value.

For increased regulating sensitivity it is also possible to set
lower values, although it is highly unadvisable to go beneath
60 % of the computed value. Higher values will cause a
decrease in regulating sensitivity.
If the measuring-circuit voltage is altered far enough during
operation to exceed the set bandwidth, the presignal will
respond. An output pulse will be generated according to the
set delay time.
If no compensation occurs for more than 15 min, the
„function monitoring“ relay will respond (see connection
diagram). The relay will not be reset until a shortfall of the
bandwidth threshold has occurred.

T1 Linear/integral
The delay time T1 can be set with linear or integral response.
If a delay time with integral response „Int“ is set, the delay
time is automatically shortened according to the relation of
actual system deviation to set bandwidth, down to a
minimum of 1 s (
fig. 2
).
The desired time behavior can be set by pressing the SET and
function keys.

Setting the delay time T1 or T2 (DELAY 1/
DELAY 2) and pulse duration (option)
The delay time starts as soon as the deviation exceeds the set
bandwidth limits above or below. At the same time the cor-
responding presignal arrow appears. If the deviation is still
present after the delay time has elapsed, an output pulse is
emitted. If the deviation returns to within bandwidth limits,
then the current delay time is cancelled immediately.
Delay time T1
The delay time can be set from 0....180 s by pressing the SET
and
function keys.
