6. Intended use
This product is designed exclusively to regulate voltage at the low voltage level (400V L-L
and special applications 230 V L-L).
7. Description and Principle of Operation
7.1 Principle of Operation
The LVRSys™ regulator concept is based on a linear regulator. By coupling and uncoupling
two transformers with a selected transfer ratio, the output voltage can be regulated in
several (e.g. 9) steps. This technique is also refered to as Buck/Boost transformers
The maximum control range depends on the model of LVRSys (e.g. from ±6% up to ±24%).
The switching of the transformers is controlled by thyristors. The regulation steps are
determined by the thyristors' various switching settings.

Table 7-1 Generation of the voltage levels in steps
The control signals for the thyristors are generated by driver circuits that switch them
intelligently. By monitoring the magnetic flux in the transformers, the transformers can be
switched without any voltage dips or current increases occuring or harmonics being
generated.
The step change required is output by the controller. The controller can determine the step
based on the bus bar voltage or the output currents.
All three phases are regulated independently of one another. This greatly helps improve the
symmetry –balancing of the 3 phases of the LV Network.
In the event of a failure the safety contactor activates automatically. This ensures that the
transformers are bridged out and as such the low-voltage grid will operate unregulated.

Figure 7-2 Example of 3% voltage reduction
In the example shown in Figure 7-2, the output voltage is reduced by 3% compared with the
input voltage.
The transformer Trafo 1 (-4.5%) converts the primary voltage, which is switched by
thyristors, in a negative direction and subtracts (bucks) 10.35 V (4.5% of 230 V) from the
output voltage.
The transformer Trafo 2 (+1.5%) converts the primary voltage in a positive direction and
adds (boosts) 3.45 V (1.5% of 230 V) to the output voltage.

7.2 Operating behavior in the low-voltage grid
The low-voltage regulation systems are designed for a long, robust use in the low-voltage
grid. In the following, grid scenarios are compared with the behavior of the low voltage
regulation systems.
Event
reaction LVRSys™
Short circuit Ph1
Fuse blow off Ph1
Automatic bypass activated for all phases
Automatic restart of the controller after replacing the
fuse
Short circuit
Ph2/Ph3
Fuse blow off Ph2/Ph3
Automatic bypass activated for all phases.
Automatic operation mode of the controller after replac-
ing the fuse
Lightning strike
All phases
Lightning protection activated
Only after several lightning strikes releases lightning rod
and separates the control system from the main voltage.
Automatic restart of the controller after replacement of
the lightning arrestor module
Voltage drop Phase
1
No reaction of the controller up to 100 V residual volt-
age. Below 100 V residual voltage, the controller goes
into automatic bypass mode
When the voltage returns, the controller automatically
switches to operating mode
Voltage drop
Phase 2/3
No reaction of the controller to 5% residual voltage. Be-
low 5% residual voltage for> 20 ms, the controller goes
into automatic bypass mode. After the voltage has re-
turned to normal, the controller automatically switches to
operating mode
Overvoltage Phase
1/2/3
No reaction of the controller up to 170% residual voltage.
Over 170% residual voltage for> 30 ms, the controller
goes into automatic bypass mode. After the voltage has
returned to normal, the controller automatically switches
to operating mode
Harmonics
harmonics have no influence on the controller
The Controller has no influence on the harmonics.
