Q&A

When logging the voltage of larger sites we suggest the standard logging for five days at the site’s incoming supply and then moving the logger to the furthest point from the supply for a day or two to ensure that we cater for voltage drop when recommending the optimisation setting. We have occasionally surprised our clients by showing them voltages of under 210V at the furthest points at their sites. This shows that equipment can and does run at these lower voltages, but we would not choose to install a powerPerfector where voltage was already lower than 220V.
