Date Code 20170814 Instruction Manual SEL-700G Relay
Metering and Monitoring
Metering
Peak demand metering values are stored to nonvolatile memory four times a
day and within one minute of the peak demand metering values being reset.
Demand metering is stored in volatile memory only and the data will be lost
when power to the relay is removed.

Relay Option Demand/Peak Demand Values
X-Side Demand/Peak
Demand Quantities
(model dependent)
➤ Demand/peak demand values of input currents IAX, IBX,
and ICX magnitudes (A primary)
➤ Demand/peak demand value of calculated current IGX
(IGX = 3I0 = IAX + IBX + ICX) magnitude (A primary)
➤ Demand/peak demand value of calculated negative-
sequence current (3I2X) magnitude (A primary)
Y-Side Demand/Peak
Demand Quantities
(model dependent)
➤ Demand/peak demand values of input currents IAY, IBY,
and ICY magnitudes (A primary)
➤ Demand/peak demand value of calculated current IGY
(IGY = 3I0 = IAY + IBY + ICY) magnitude (A primary)
➤ Demand/peak demand value of calculated negative-
sequence current (3I2Y) magnitude (A primary)
