AUTO-RANGING POWER / ENERGY
All power quantities auto-range to display units relative to the
nominal power of the system as defined below. Multiply the
power quantity in question by the multiplier in register 0316h to
yield the correct reading. The SI prefix for all power and
energy quantities before scaling by the multiplier is ‘k’. All
power quantities are signed, single word registers (F4).
All energy quantities are unsigned, double word registers (F7).
The multiplier is determined from the nominal power which is
defined as the product of three setpoints: P
N
= Phase CT
Primary x Bus VT Secondary Voltage x Bus VT Ratio
Example: If the 3φ Real Power register (0310) has a value of
‘123’ and the Multiplier register (0316) has a value of ‘10’ then
the value to display is 1230 kW.
