[Fig. 20]
Graphic display of the voltage harmonics referring to the single-phases.
Use the SEL and SET keys to scroll through the measured values of the harmonics appearing on the
right top of the page. Example : H 05 90.32 V L2 means the 5th voltage harmonics of phase 2 has
a value of 90.32 Volt.
Note : This page appears only in the HARMO model.

Total apparent energy counter
Total active energy counter
Note: range 0,000,000.00-99,999,999.9. When the upper limit is reached, the counter restarts from 0.00.

Total reactive energy counter
Total active energy counter
Note: range 0,000,000.00-99,999,999.9. When the upper limit is reached, the counter restarts from 0.00.

Total exported active energy
Note: o measure properly the cogeneration counters it is strictly necessary to connect the
CTs oriented in the same direction.

V = (V L1-N + V L2-N + V L3-N ) / 3
V = (V L1-L2 + V L2-L3 + V L3-L1 ) / 3 (3 PH)
V = V L1-N + V L2-N
V= V L1-N
A = S / (3 V)
A = S / V
A = A L1
P = P L1 + P L2 + P L3
P = P L1 + P L2
P = P L1
P.F. = P / S
S = ( P 2 + Q 2 )
Q = Q L1 + Q L2 + Q L3
Q = Q L1 + Q L2
