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.
