Power Factor Correction Solutions - 31

ABB Power Quality

ABB is unique as a UK manufacturer offering a complete power quality
service for networks from low (LV) to high voltage (HV), including power
factor correction (PFC) and active harmonic filtering equipment. ABB's
expert team provides comprehensive consultancy services that help
customers to identify their power quality issue and can then deliver the
perfect solution, either using off the shelf or bespoke equipment. The
benefits of getting power quality right include:

• Load reduction to make better use of existing power network
infrastructure

• Reduced energy costs & CO2 emissions

• Elimination of system harmonic distortion to meet ENA G5/4-1
requirements

Low Voltage Power Factor Correction Solutions

Reactive power, often referred to as “useless” power, builds up magnetic
fields. Incorrect management of reactive power can give rise to losses in
machinery and components as well as affecting power transmission
voltages, limiting the utilisation of electrical equipment and attracting
unnecessary extra penalty charges on electricity bills. ABB automatic
capacitor banks offer:

• Proven technology

• Wall & floor mounted options

• Complete auto set-up

• Easy to install & operate using our RVC & RVT power factor controllers

• Safety & reliability

We also provide individual capacitor shelves that enable panel builders
to incorporate ABB's PFC technology within their own low voltage panels.

Detuned Installations & Network Studies

The presence of harmonic currents can cause unacceptable disturbances
in the supply network, and adversely affect the operation of other
electrical equipment, including power factor correction capacitors.
On request, ABB’s power quality specialists will carry out a harmonic
study of the network. If harmonics are present, we offer suitable capacitor
and active filter solutions.

Active Harmonic Filters

ABB PQF active filters offer the following system benefits:

• Reduced power system downtime to avoid expensive losses of
production

• Increased system efficiency & reduction of CO2 emissions

• Compliance with the strictest power quality regulations thanks to a
unique control concept, avoiding penalties and/or refusal by utilities
to connect installations to the electrical grid

• No detailed network analysis required, with rapid & easy solution
implementation of the solution

• Not over-loadable, thanks to the active concept, hence well adapted
to LV installations where loads are upgraded frequently

Power Quality Surveys

ABB offers a free no-obligation power quality survey. We then work with
you to design and install the ideal power factor solution for your site.

Total Service Approach

ABB is committed to a total power quality equipment and service
approach that goes well beyond supplying just the equipment. Thanks to
the unrivalled technical backup of the global ABB organisation, we
support our customers through every step of the project, from establishing
the problem, identifying the ideal solution and then installing and
commissioning your power quality equipment.
