Transient voltages at an industrial facility caused by utility capacitor switching

Technical Report ·
OSTI ID:376843
This paper describes concerns for capacitor switching transients within customer facilities. Magnification of transients initiated at higher voltage capacitors and tripping of sensitive variable frequency drive (VFD) loads are evaluated in particular. The results of measurements and simulations associated with capacitor switching on the Public Service Company of New Mexico system and the resulting impacts at an Intel plant are presented. These results illustrate the important effect of customer load characteristics on the transients experienced within the facilities.
