Chapter 4 Wizards Innovation Series Medium Voltage GP Type - G Drives GEH-6385
Line Protection: Overfrequency
These parameters set the level of protection of the ac line overfrequency protection.
It is highly recommended to use the control default values as calculated in the
previous steps (you can go backward).
• Over freq flt level is the ac line frequency above which the AC line over freq trip
fault occurs.
• Over freq alm level is the ac line frequency above which the AC line freq high
alarm occurs.
• Over freq alm clear is the ac line frequency below which the AC line freq high
alarm goes away.

Line Protection: Underfrequency
These parameters set the level of protection of the ac line underfrequency protection.
It is highly recommended to use the control default values as calculated in the
previous steps (you can go backward).
• Under freq flt level is the ac line frequency below which the AC line under freq
trip fault occurs.
• Under freq alm level is the ac line frequency below which the AC line freq low
alarm occurs.
• Under freq alarm clr is the ac line frequency above which the AC line freq low
alarm goes away.

Line Protection: Conclusion
You have completed the Line Protection Setup wizard. The control is now ready to
run with the new values after the parameter upload.
Pulse Test
Pulse Test: Introduction
The Pulse Test wizard is a diagnostic tool which allows the user to produce voltage
pulses using the power bridge. Such pulses and the resulting currents which are
induced are useful in performing detailed analysis of the load or power bridge. The
bridge is capable of performing a number of different types of voltage pulses and so
the wizard is more complicated than might be expected.
In general the Pulse Test user specifies the power bridge devices used to make the
voltage pulses and the duration of the pulses.
