The modular PQC range enables to reach a power factor close to one by correcting at a very affordable cost both the reactive energy and the most dominant harmonics.

With the continued installation of power electronic devices such as motor speed control by means of variable frequency drives or electronic ballast for lighting and process controllers, harmonics are a critical concern.  (Please note that those need to be measured in current and not only in voltage as often thought).

Those harmonics can be corrected with a filter integrated in the device by the OEM (this is required for application with an input below 16A per phase).  For higher power, the extra cost for such filtering is generally by far exceeding the cost of an external filter.

Passive filters require intensive engineering knowledge and are designed for a specific configuration network.  Full active harmonic filters, mandatory in  the most demanding applications (weak circuits, isolated circuits …), are often perceived as too expensive for many industries.  As a result most industries do not correct their harmonics with uncontrolled consequences such as unexplained changes in relays or unexpected activation of protections, perturbation of field buses, counter electromagnetic forces in motors, reduced capacity of the network, increased losses, internal temperature increase of transformers, reduced lifetime of equipment.

The PQC opens new opportunities to optimise industrial power circuits.  It offers the following attractive benefits.

  • Full exact reactive power compensation on each phase
  • From inductive to capacitive mode, user settable cos phi target
  • Elimination of odd harmonics till 11th order
  • Secured load balancing between phases
  • Fast response time
  • Modularity and scalability
  • Unlimited parallel operation
  • Enhanced reliability and protection modes

The PQC can be delivered as rack mounted or wall mounted modules which can be easily installed in parallel anywhere on the electrical line. As the system can be easily upgraded, it is not necessary to over-dimension the capacity to take into account future needs. Indoor large systems can be achieved by paralleling cabinets each delivering up to 500kVAR.   IP 54 solutions are also available when the equipment needs to be installed in harsh environments.

SVG is the new standard in var compensation. SVG is connected in parallel to the grid, similar to a variable var current source. SVGs fundamental configuration are 3-phase self commutated bridge circuits adopting full controlled power electronic semiconductor devices (IGBT). By adjusting the output voltage amplitude and phase angle or direct controlling AC side current, the SVG can absorb or generate var according to the loads reactive power or the grid voltage level.

The Static Var Generator achieves the fastest PFC speed. A real-time PFC according to the changes of reactive current in the system. The Static Var Generator issues offset current with equal size and opposite phase of reactive current. When compensation current reverses, reactive power in the system completely overlaps with the wave form of the reactive power issued bij the SVG.

Electronic voltage optimizers, regulators and conditioners allow commercial enterprises of any size to optimize voltage to match individual facility needs, exactly. Voltage conditioners safely bridge voltage anomalies and ensure maximum uptime and motor life for valuable production equipment, while safely operating on grid voltage.

The automatic voltage conditioners provide tightly controlled voltage through both transient and longer-term low or high voltage events, while balancing 3-phase power.

Power made perfect

  • Fast voltage regulation corrects under/over voltage, sags, and swells (full correction within one cycle)
  • High fault-clearing capacity permits reliable operation of other protective devices
  • Built-in surge suppression for surges and spikes
  • Line isolation minimizes transients
  • Transformer shielding reduces line noise to deliver clean power
  • Independent phase regulation corrects voltage imbalance
  • Input circuit breaker protects against damaging over-current and short circuits
  • Automatic failsafe electronic bypass keeps the load powered

The WSP electronic voltage optimizers, regulators and conditioners combine the best qualities of typical mechanical and electronic voltage regulators while eliminating their weaknesses. Mechanical voltage regulators are valued for their high overload capacity and good voltage regulation, but these qualities are offset by their slow correction speed and the need for regular maintenance of moving parts. Similarly, electronic voltage regulators are known for their fast correction speed, but suffer from poor overload capacity.

The WSP electronic voltage regulators and conditioners provide high overload capacity for loads with large inrush-current requirements. At the same time, it provides consistent voltage regulation and fast correction without regular maintenance or moving parts.

The smart city applications are a subsequent expansion. Each lighting mast is a terminal for cameras, WIFI, traffic measurement, measurement of weather conditions and air pollution, alarm points and all other applications that make a city smart, comfortable and safe. The smart city is a gradual evolution on the basis of requirements and budgetary possibilities. Population and policymakers determine to what extent the smart city should take form.

Energy savings and CO2-emission reduction in lighting of public areas are today’s goal, while security of people and infrastructure remain highly critical. The Minos product range offers realistic opportunities to initiate and upgrade the infrastructure. Powerline technology offers two significant benefits: scalability and signal security.

The use of power line transmission enables the Minos System to communicate with each single lighting point exploiting the existing electric line, without adding any new and expensive cable. Thanks to this technology, the system allows to decide in which particular area to operate and in which time to send ON/OFF and flux reduction commands to the lighting points. Moreover we can also get all the information about the status and/or malfunctioning of each lamp.

Power made wise

  • Energy savings from 20% to 45%
  • Easy scalable and optimal signal security
  • Remote control of each lighting point
  • Maintenance in real time 
  • Reduction of light pollution
  • Dedicated lighting network management software

The Minos System helps to respect the environment and the targets established in the International agreements. Thanks to the energy saving and the maintenance intervention scheduling, it decreases fossil fuel consumption, thus reducing greenhouse gas emission in the atmosphere. Moreover, when signalling the damages, it eliminates wastes a lamp can emit. Finally, it allows reducing the light pollution thanks to the possibility to decide when to turn on/off or to reduce the lighting flux of the single lighting point.
