Smart Load Shed Scheme

Smart Load Shed Scheme
• Scheme uses Multilin UR relays (F35, F60, G60, etc.)
connected via Ethernet network to calculate power at
locations throughout facility
• Analog power values are sent to master C90Plus control and
programmable logic within C90Plus determines loads to
shed based on user configuration
• C90Plus controller capable of communicating to 32 UR
relays located throughout facility
• Smart load shed scheme capable of selecting the next loads
to shed based on current profitability of the process or other
predetermined criteria
