Early Learning

Project ran from July 2011 - February 2013

Project Description

A new low carbon housing development of roughly twenty houses which have been developed by Melin Homes in Crickhowell, South Wales. The estate features high efficiency houses each equipped with photovoltaics. Traditional network studies indicate that voltage limits would be exceeded without an overlay of existing 95sq mm LV cable. The scheme provided a low cost opportunity for early learning of photovoltaic (PV) voltage impacts and validity of existing electricity network design assumptions. Installation of two different size LV cables in parallel to the existing cable, with linking facilities at each end, provided a real life, on load, capability to change the impedance of the feeding LV cable and measure resulting changes in voltage performance.

Areas of Work

  • Voltage rise on LV cables 
  • Domestic photovoltaics
  • Low voltage network design and optimisation
  • Avoidance of excursions of statutory voltage limits
  • Appropriate cable sizing
