Mid-Carolina Electric Cooperative (MCEC) replaced their hydraulic reclosers with solid dielectric reclosers and microprocessor-based recloser controls as part of a program to modernize their distribution system. MCEC was having problems with hydraulic reclosers, including excess maintenance costs and poor repeatability of the time-overcurrent trip characteristic. As part of the replacement, they expected...

Distribution substations at electric cooperatives and municipal utilities have historically involved simple protection schemes consisting of feeder circuit overcurrent, reclosing, and transformer protection, either with high-side fuses or differential and overcurrent protection. These protective devices have served to protect the transmission operator as much or more than the distribution substation...
