Measurement Function; Active Power; Integrated Power Amount - Omron KE1 User Manual

 Measurement function
 Active power
PGR1C PVS1C
(Electric power (Electric power
/leakage) /voltage sag)
○ ○
O: With measurement function X: Without measurement function
Measurement range: -99999999.9 to 99999999.9 W (minimum unit: 0.1 W)
The following active powers are measured: instantaneous value, maximum value, and
minimum value.
The active power means a consumed power. Power that is generating electricity is referred to
as regenerated power.
The logging function allows storing the max. and min. values. (Note 1)
Note 1: CTD8E (CT extension) cannot store the values with the logging function not provided.
 Integrated power amount
PGR1C PVS1C
(Electric power (Electric power
/leakage) /voltage sag)
○ ○
O: With measurement function X: Without measurement function
Measurement range: Excess of the measurement range of 0 to 999999999 Wh returns to 0
Wh, continuing the integration.
Power consumption (active power) and reverse power (regenerated power) are integrated
separated from each other. After the conversion of VT and CT ratios, power is also integrated.
Reactive power is also integrated. Via communication, integrated progression reactive power
amount, integrated delayed reactive power amount and integrated total reactive power
amount can be confirmed in units of varh. Each measurable amount is up to 999999999 varh.
When each amount measured reaches 999999999 varh, it is reset to 0 varh. The reactive
power amount to be integrated is divided into the three types: phase progression reactive
power, phase delayed reactive power, and total reactive power of phase progression and
phase delayed absolute values.
 Definitions of phase progression and phase delayed of integrated reactive power amount
Whether the active power is active or regenerated, the integration progression reactive power
amount is integrated in the case of phase progression, and integrated delayed reactive power
amount is integrated in the case of phase delayed. In addition, for the integrated total reactive
power amount, the absolute value of progression reactive power amount and the absolute
value of delayed reactive power amount are integrated. The progression and delayed reactive
power amounts are calculated according to the phase of the voltage based current.
