Monitoring the Inverter

975-0466-01-01
The protection timer begins its countdown during startup and the
Reconnecting in
sss seconds
screen appears until the timer countdown is complete.
Vpl=
0V
Clr t < 0.20s
3 seconds
Vpl:
phase-to-neutral (rms) low threshold voltage
setting.
Note
: Phase-to-neutral threshold voltages
are disabled for Australian GT Inverter models so
this screen always displays
0V
.
Clr t:
clear time.
Fh= 51.0Hz
Clr t < 0.15s
3 seconds
Fh:
frequency high threshold setting, the threshold
at which the inverter disconnects itself from the
power grid when abnormally high frequency is
detected.
Clr t:
clear time.
Fl= 48.0Hz
Clr t < 3.10s
3 seconds
Fl:
frequency low threshold setting, the threshold
at which the inverter disconnects itself from the
power grid when abnormally low frequency is
detected.
Clr t:
clear time.
Reconnect Delay
185.00s
3 seconds Setting for the reconnect delay for the protection
timer. After a fault clears for the specified clear
time, the protection timer starts counting down
before the inverter attempts to deliver power to the
grid.
* All numbers in this and following tables are examples only. Your model,
revision numbers, and performance data will vary.
† The voltage and frequency thresholds, clear times and reconnect delay in
Table 5-1 can be adjusted for multi-unit installations producing 30 kW or more
(with the permission of the local utility) using GTConfigLite software.
‡ The clear time is the total time to disconnect the output from the grid. It is the
sum of the debounce time and the hardware delay time. The debounce time is
the protection processor waiting time before it declares a fault. This delay is
necessary to avoid nuisance trips.
