A customer at an aerospace manufacturer in the Isle of White wanted an end of life replacement for their existing Power Factor Correction units.
The existing units were 150kVAr each in a Master/Slave set up, meaning that one of the units controlled both. The reason for this set up was because the LV board was split into to two separate supplies and the PFC unit had been installed with a summated C.T circuit.
The like for like replacement of the PFC units meant we were able to re-use the existing power cables, C.T circuits and control cable. All works were completed during normal working hours without any disruption to the site.
