Voltage Conversion

To support long-term system performance and reduce equipment strain, Allgeier Martin designed a voltage conversion for a city in Central Missouri. The project began in 2015 at an existing step-down transformer, which was replaced with a 15 kV sectionalizing/junction cabinet to initiate the upgrade. The conversion increased the system voltage from 4,160 V to 12,470 V, with additional underground work upgrading 87 homes from 2,400 V to 7,200 V. Because the existing conductor was already insulated for higher voltage, no replacement was needed. New pad-mount transformers, sectionalizing/junction cabinets, and dual-voltage overhead transformers were installed to complete the conversion. The project was completed in 2019, on time and under budget.
