With ever rising copper prices, are you now spending far
too much on those long "over-sized" electrical cable
runs - essential to compensate for the inherent voltage drop? |

Our
NEW
range of, both outdoor and indoor, cost efficient
Voltage Compensators enable you to “compensate”
for these expensive voltage drops, by boosting up
voltage and keeping it constant - ensuring you are able
to make
SUBSTANTIAL
savings on your electrical power cable costs. |

Why install a Constant Voltage
Compensator?
What is the Ideal Solution?

Why
install a Constant Voltage Compensator?
Installations with long cable runs have an inherent problem
of developing high voltage drops across their cables. To
overcome this it is necessary to select and use larger sized
electrical cables in order to reduce such voltage drops to an acceptable
level.
IEE Regulations stipulate that a volt drop should be no more
than 4% which means that for a 400V system the drop across any
length of its cable should not exceed 16 volts. So as an
example, if a supply voltage is 400V on the transmission end
then the voltage at the other end of the cable should not be
less than 384V.
In addition to a cable voltage drop, main supply voltages
have a permissible fluctuation range of +/- 6%, providing the
mains supply is connected directly to the supply authority. If
this is not case then fluctuating mains voltages may be even
higher due to the various loads which may be connected (plus
load changing conditions) in between.
Taking into consideration these various factors it is
apparent that the overall voltage drop at the end point of a
cable can be quite substantial. To meet IEE requirements, it is
essential to select a correctly sized and rated cable to keep
within the permissible volt drop levels for each installation.
In recent years copper prices have risen significantly and
under IEE compliant situations the choice of power cable size can now
have a really significant impact on project installation costs.

What is the Ideal
Solution?
Our Ashley Edison Constant Voltage Compensator ranges have
been carefully designed with meeting IEE requirements. With the
Compensator installed at the end of the cable where the volt
drop is high, it will continuously monitor and adjust the
voltage to help maintain a constant voltage within +/-1.5%
accuracy. In our example the cable end voltage will then be a
constant 400V (+/-1.5%) - complying fully with IEE requirements.
With the cable sized and selected / rated to ensure minimum cost for
an installations requirement the combined cable and Compensator
costs will definitely show a substantial overall saving.
Another major advantage to incorporating a Compensator in an
installation is that the output voltage may be linearly adjusted
to suit load equipments input voltage requirements. eg. An
output voltage may be set to within 400V +/-10% whilst still
maintaining the output accuracy of +/-1.5%. The Compensator is
free from any harmonic emissions.
Both indoor and outdoor versions are available and include
many protective features such as Surge Suppression and
Lightening Arrestors (these are just a few) to help protect
loads from potential problems.
Our Compensators can boost voltages from as low as 208V 3
Phase and maintain a 400V 3 Phase at the output to its load.
As a one stop solution to an unacceptable volt drop situation
on a cable run, many installers have typically resorted to the
inclusion of additional Step-Up Transformers or Booster
Transformers in their systems.
This has disadvantages:-
1. The input voltage is not stable and any Step-Up increase
in voltage will be transformed to the load end and be harmful to
load equipment. This could equally apply to any Step-Down /
decrease in supply voltage.
2. The voltage between no - load and full - load conditions
may be quite substantial and the voltage difference could also
cause damage to the load equipment.
There is absolutely no control over such changes without a
Voltage Drop Compensator.
