TOR Engineering was founded by the late Thomas O. Radnoti (TOR) in 1985, with headquarters in Phoenix, Arizona. Tom instilled ... a great sense of pride and professionalism in our engineering services and these qualities continue in our firm to this day. The principals and registered engineers of TOR Engineering have been providing professional engineering services since 1969. Our primary areas of expertise are electrical and structural engineering. Since the beginning, we have focused on serving the utility related electrical community. We specialize in substation, transmission, and distribution design. Our substation design experience ranges from additions to rebuilds to complete new stations. These stations are at all voltage levels, up to 500kV. Our transmission line design expertise includes all voltage levels. We also have an extensive distribution design background, both overhead and underground. These projects include underground conversions of existing overhead lines, relocations, upgrades, new lines, equipment, services, and street lighting. TOR Engineering has also performed short circuit, powerflow, coordination, and capacitor application studies for our clients. More recently we have included the additional services of commercial, institutional, and residential electrical and structural design to our team. read more
