Electrical power supplied directly from Westar is distributed at 12,470 volts to the buildings on campus. Transformers located near most buildings further step down electricity to 480, 277, 208, and 120 volts.
As transformers are taken out of service because of age, malfunction, or obsolescence, they are replaced by ones with similar capacity that are owned by Westar. All transformers owned by the university have been tested by an Environmental Protection Agency approved laboratory for the concentration of PCBs (polychlorinated biphenyl's). PCBs are a family of 209 manufactured chlorinated organic chemicals widely used in electrical equipment. Because of their toxicity, PCBs are regulated by the EPA. Transformers containing concentrations of PCBs greater than 500 PPM (parts per million) are no longer allowed near public buildings. All transformers containing PCBs in concentrations greater than 500 PPM have been removed from campus and disposed of by a licensed contractor according to federal regulations.
