SPQ

Smart Power Quality

Designed for outdoor installations and comes with IP44 enclosure and intended for installation on supply transformers secondary side. The unit will perform 3-phase load balancing, VAR compensation, and optional harmonic mitigation.

The SPQ is based on an upgraded SVG, or ASVG mounted inside a stainless steel enclosure complete with protections and built-in WiFi for easy diagnostics. The SPQ is specialized for the increased power quality issues found on distribution networks and has the following functions; three-phased unbalanced compensation, fast step-less regulation of reactive power, and system voltage stabilization. The SPQ can also be equipped with harmonic mitigation capacity if needed. The SPQ is ideal for mounting outside when there is no room left in a plant switchboard room or for mounting up a pole for electricity network applications. SPQ is available in 30/50/100kVAR in two cabinet size options. The SPQ offers all the features of the SVG / ASVG as a complete stand-alone system.

Key Features

• Superb power factor correction performance
  that maintains a PF of 0.99 lagging or unity if
  required.
• Compensates both inductive and capacitive
  loads from -1 to +1 power factor.
• Dynamic step-less compensation profiles the
  load and operates with a reaction time of 50μs
  and response time with full correction in less
  than 15ms.
• No possibility of over-compensation or
  under-compensation
• Will only inject the kVAR that is required at
  any specific moment.
• Corrects load imbalance
• Harmonic mitigation (ASVG) of 3rd, 5th, 7th,
  11th harmonic orders
• Unit capacity can be shared 50/50 between
  power factor and harmonics correction
• Operates at low voltages
• Can be used with existing PFC systems
• Suitable for mounting up a power pole
• Automatic voltage regulation
• Stainless steel IP44 outdoor rated enclosure
• MCB and class C overvoltage surge protection
  against indirect lightning discharge
• Not affected by resonance
• Parallel connected, so larger capacities are
  obtained
