Overhead Capacitor Banks

Scott offers OH capacitor rack solutions engineered to meet a variety of application needs. Our packages deliver improved power factor, increased system capacity, better power flow, reduced losses, and overall cost savings.

 

Each overhead rack ships fully assembled with high‑voltage wiring, capacitors, switches, VTs, wildlife protection, and optional accessories. Units support single‑ or three‑phase configurations and operate from 5 kV to 34.5 kV, with capacities up to 1,800 KVAR. Every rack is engineered to meet applicable local seismic and wind requirements.
