Maple Avenue Substation Renewal

CHA made design modifications to Cornell University's 115 kV substation to replace existing transformers by three 115/13.2 kV 20/26.67/33.33 MVA power transformers. New equipment included:

  • 115 kV circuit switchers
  • Disconnect switches
  • CVTs
  • 13.2 kV ring bus switchgear lineup
  • 13.2 kV zig zag transformers
  • Electrical protection monitoring system
  • 125 VDC redundant battery system
  • NYSEG revenue metering and RTUs
  • New switchgear
  • Control building

The modification was required to accommodate the addition of a new combined heat and power plant and meet the demand of the campus electrical load growth with improved reliability.
