7.7. "ENERGY" FUNCTION
This function permits to display the values of phase and total active powers, phase and
total capacitive and inductive reactive powers, power factors and phase and total cos

.
Furthermore, the instrument is able to measure directly (see 7.7.2) the values of phase
and total active energies and the values of phase and total capacitive and inductive
reactive energies.
7.7.1. Symbols
The position ENERGY has one working mode:
 METER
This mode will be described in detail in the next paragraphs.
The symbols used are described below:
Symbol Description
Pt, P1, P2, P3 Values of active power (total, phase 1, phase 2, phase 3 respectively)
P12, P32 (only for 3-wire measurement) Value of power measured by Wattmeter 1-2 and 3-2
respectively
Qt, Q1, Q2, Q3 Values of reactive power (total, phase 1, phase 2, phase 3 respectively)
Q12, Q32 (only for 3-wire measurement) Value of power measured by VARmeter 1-2 and 3-2
respectively
St, S1, S2, S3 Values of the apparent power (total, phase 1, phase 2, phase 3 respectively)
S12, S32 (only for 3-wire measurement) Value of power measured by VAmeter 1-2 and 3-2
respectively
Eat, Ea1, Ea2, Ea3 Values of active energy (total, phase 1, phase 2, phase 3 respectively)
Erit, Eri1, Eri2, Eri3 Values of inductive reactive energy (total, phase 1, phase 2, phase 3 respectively)
Erct, Erc1, Erc2, Erc3 Values of capacitive reactive Energy (total, phase 1, phase 2, phase 3 respectively)
Est, Es1, Es2, Es3 Values of apparent energy (total, phase 1, phase 2, phase 3 respectively)
Tab. 4: Symbols used in the ENERGY function
The symbols "i" and "c" stand for reactive powers (Q) and energies (Er), inductive and
capacitive respectively.
