
Phase-phase voltage
L
= Primary rated voltage* 0.9 * √3
H
= Primary rated voltage * 1.1 * √3
Min = L * 0.8 Max = H * 1.2
P
L
= L + (( H - L ) * 0.1) P
H
= H - (( H - L ) * 0.1)

Current
L
= 0
H
= Primary current
Min = 0 Max = H * 1.2
P
L
= 0 P
H
= H - (( H - L ) * 0.1)
The alarm and pre-alarm zones L are not displayed.

Power ratings
L = 0 H = Primary rated voltage * Primary current
Min = 0 Max = H * 1.2
P
L
= 0 P
H
= H - (( H - L ) * 0.1)
The alarm and pre-alarm zones L are not displayed.

Frequency 50 Hz
L
= 45
H
= 55
Min = L * 0.95 Max = H * 1.05
P
L
= L + (( H - L ) * 0.25) P
H
= H - (( H - L ) * 0.25)

Frequency 60 Hz
L = 55 H = 65
Min = L * 0.95 Max = H * 1.05
P
L
= L + (( H - L ) * 0.25) P
H
= H - (( H - L ) * 0.25)

Voltage THD
L = 0 H = 5
Min =0 Max = H * 2
P
L
= L + (( H - L ) * 0.25) P
H
= H - (( H - L ) * 0.25)
The alarm and pre-alarm zones L are not displayed.

Current THD
L
= 0
H
= 20
Min =0 Max = H * 2
P
L
= L + (( H - L ) * 0.25) P
H
= H - (( H - L ) * 0.25)
The alarm and pre-alarm zones L are not displayed.
