Increasing in Information Technology also increase the use of computer and printer at home. On other hand the energy crisis causing "Saving Energy Lamp" (LHE) become largely used nowadays. Computer, Printer and "Saving Energy Lamp" are non linear load that cause a power harmonic distortion in the power system distribution grid, including in the pole-mounted transformer. The harmonic current that can caused transformer losses can be measured at pole-mounted transformer. In conclusion, increasing load at pole-mounted transformer (83,14%) will raise losses at load (6%) and current THD (Total Harmonic Distortion) (18.3%). In this measurement the current harmonic is higher than standard THD (8%).
