6.1.3 Active Current
IP
The display shows the active current on
the fundamental oscillation in the current
transformer (CT) circuit. The LED
"Ampere" lights up.
The current direction is also displayed
which is helpful during tests. The LED
"Regen" shows that the generative active
power is fed back into the mains. If the CT
ratio is programmed into the relay, the ac-
tual active current is displayed; otherwise
the current portion is displayed and must
be multiplied by the CT ratio to
obtain the actual value.
Press "IQ", "IP", or "Harm" buttons to exit
the display.
6.1.4 Apparent Current
IQ IP
Pressing the "IQ" and "IP" buttons simul-
taneously activates the display. The LED
"Ampere" lights up. If the CT ratio is pro-
grammed into the relay, the actual
apparent current on the fundamental
oscillation in the current transformer (CT)
circuit is displayed; otherwise the current
portion is displayed and must be multiplied
by the CT ratio to obtain the actual value.
Press "IQ", "IP", or "Harm" buttons to exit
the display.
6.1.5 Harmonics (5
th
- 13
th
)
Harm
This display shows the 5
th
, 7
th
, 11
th
, and
13
th
harmonics on voltage. The previous
harmonic reading appears on the display
(in %) and the LED "Harmonic" lights up.
By pressing the "+" or "-" buttons several
times the portions of the 5
th
, 7
th
, 11
th
, and
13
th
harmonics are subsequently displayed
either in ascending or descending order.
For example. if "5. 2.9" is displayed this
means "5
th
harmonics = 2.9 %".
Press the "Harm" button to exit the
display.
6.2 Manual Operation
man
Set
When the "man/Set" button is pressed for
more than 3 secs, the control relay
switches to manual operation and the LED
"manual" begins to flash. The capacitor
stages can be switched on or off by press-
ing the "+" or "-" button.
