Ashburton Water Treatment Plant Arc Flash Improvements

(Baltimore, MD)

Design, supply and management of low voltage switchgear modifcations, existing
PLC and SCADA systems at one of Baltimore City's main water treatment
facilities. BDE LLC supplied a custom UL508 PLC control panel, remote breaker
control cabinet (RBCC) and modification services. The customer planned to add a
new generator to the existing scheme which involved Eaton low voltage
switchgear, GE HMI and Modicon PLC. BDE modified switchgear cells to accept
new generator breakers, installed Shark meters, SPD, RBCC and integrated a new
PLC which functions the updated auto throwover scheme. Arc flash mitigating
trip units were also added to the existing main, tie breakers for Baltimore City
personnel safety.
