Case Studies
Explore detailed case studies showing how PFC Engineering Ltd has supported customers with their energy-saving requirements through tailored engineering solutions and expert guidance.
Power Quality – Case Study
Investigation of a Power Quality issue at a major electronic components distributor, where repeated failure of the communication system operating multiple conveyors was costing thousands of pounds per hours in lost product throughput.
Power Factor Correction – Case Study 1
A sites poor Power Factor was causing excessive amounts of reactive power, leading to high reactive charges on their electricity bills. Following a site survey and load check it was found that by installing Power Factor Correction, site could save on average £1,500 per month.
Voltage Optimisation – Case Study
On a large leisure complex, the site voltage was peeking at around 250V(L-N). When Voltage Optimisation was installed, it reduced the site voltage output down to 221V (L-N), savings of over £76,000 were made in as little as 10months, as well as a significant reduction in carbon emissions.
Detuned Power Factor Correction – Case Study
When a large plastics factory needed to increase their infostructure, they also required more Power Factor Correction equipment to keep on top of the kVAr demand. During a site survey, harmonic distortion of over 8% was measured, far above the onsite equipment’s IEC compatibility limits. The standard PFC equipment on site was only exacerbating the issue. By Installing detuned Power Factor, these excessive harmonics could be reduced down to safer levels.
Power Factor Correction – Case Study 2
A Power Factor of 0.71 inductive was causing a large packaging company around £250 per month in reactive charges on their electricity bills. By installing Power Factor correction equipment, bringing their average Power Factor above 0.95 inductive would save them almost £7,000 per Annum.
Load Reduction – Case Study
After we were contacted by site to investigate the recurrent failure of the site’s main electricity supply fuses. Following a site survey, it was found that site also had Fixed and automatic Power Factor Correction equipment that had not been serviced. A load analysis was carried out and recommendations were put forward to not only prevent the site from losing its supply fuses but also reduced their energy costs by improving the sites Power Factor.
