Our Approach
The European harmonised voltage is currently nominally 230VAC single
phase. Electricity utility suppliers often provide a system voltage
higher than this in normal operation, typically in the region of 235 to
250V, which allows for potential losses and a generous safety margin.
Most lamps and luminaires, but not all, are designed to run on single
phase voltage and actual lamp specifications allow for an operating
voltage down to 207 VAC Line to Neutral without any significant change
in colour rendering or noticeable Lux reductions. The over voltage and
its product, current and power, is wasted in the form of additional
light, unwanted heat and reduced component life of lamps and
luminaires. The concept behind
the Opt-i-Mizer controller
is to capture
and reduce the over voltage and to provide a reduction in the
amount of energy consumed by the lamp circuit after the initial
start-up phase. The fluoresave
controller achieves a similar effect by using an auto-transformer to
step-down the over-voltage.
In order that we can evaluate the most appropriate controller and
hence the maximum savings potential of the lighting installation,
a survey should be undertaken
to identify the
existing lamp types, supply voltage and power load for each circuit or
distribution board. The information gained from the survey forms the
basis of the savings evaluation report and identifies the most
appropriate solution product.
The trial
installation is an important stage and this enables us to
test the actual optimal voltage reduction that can be achieved in situ
and hence calculate the real savings that can be obtained from the
controller. Sometimes a trial unit can be installed at the site survey
but more usually this is undertaken after the survey report. A final
cost and energy savings report
is produced by EOL detailing the voltage reduction, reduced power
consumption and value of the savings together with our
solution
recommendations. The installation and
commissioning is undertaken once the savings report has
been reviewed, accepted
and all approvals obtained.
