The metered values for real, reactive, and apparent power, as well as power factor, are displayed in this menu. The "SRC
1" text is replaced by whatever name was programmed by the user for the associated source (see
SETTINGS
SYSTEM
SETUP
SIGNAL SOURCES
).
When VTs are configured in wye, the T60 calculates power in each phase and three-phase power is measured as
S = V
A
x Î

When VTs are configured in delta, the T60 does not calculate power in each phase and three-phase power is measured as
S = V

ENERGY
The metered values for real and reactive energy are displayed in this menu. The "SRC 1" text will be replaced by whatever
name was programmed by the user for the associated source (see
SETTINGS
SYSTEM SETUP
SIGNAL SOURCES
).
Because energy values are accumulated, these values should be recorded and then reset immediately prior to changing
CT or VT characteristics.
