Harmonic mitigation and
power factor correction solutions from
Westek Electronics for a leaner and greener
Australia
"The
fact is that much electrical energy
generated is wasted in losses caused by
harmonics!
The fact is that excess copper is
designed-in for many commercial building
electrical installations to cope with
harmonics!
The fact is that harmonic voltage distortion
is responsible for IT and process control
computer malfunctions!
The fact is that harmonics mitigation and
power factor correction reduce our carbon
footprint!"
Commercial and industrial electrical
installations these days have to cope with
mainly harmonic-rich currents—in other
words, highly distorted current. Loads such
as variable speed drive for mechanical
services, electronic ballasts and IT
equipment in commercial buildings are the
chief cause. In industrial plant, variable
speed drives, robotic welders, induction
heaters, electrolytic plating, etc. are
frequent culprits. In addition harmonics
plus reactive loads make for poor power
factors thus frequently attracting penalty
charges from electricity suppliers.
Effective mitigation of harmonics and
improving power factor is a job for experts.
We at Westek Electronics can work with you
and your consulting engineers, on
appropriate mitigation measures—we do not
market single solutions!
At Westek we know that cleaning up voltage
and current distortion and minimising
electrical energy losses requires
multi-targeted approaches to reticulation
systems. We have available an armory
comprising of:
Rather than selling product,
we sell solutions and we do this by
providing suitable power line analysers,
capable of providing a comprehensive picture
of harmonics and other power disturbance.
After site analysis can offer solutions by
sitting down with your engineers, looking at
the reticulation line diagrams, evaluating
the possibility of segregating certain
loads, taking account of load variability
and then provide you with appropriate
measures including MTE broadband filters and
chokes, and Schaffner ECOSine active
filters.
