The 1 pu value for V/Hz operation is the Nominal Voltage setting divided by the Nominal Frequency
setting adjusted in the
General Settings menu.
The characteristics of the inverse curves are shown below:
•
DEFINITE TIME: T (sec) = TD Multiplier.
•
INVERSE CURVE A:
where:
T = operating time
TDM = Time Delay Multiplier (sec)
V = fundamental value of voltage (pu)
F=frequency of voltage signal (pu)
Pickup= volts-per-hertz pickup setpoint (pu)
•
INVERSE CURVE B:
where:
T = operating time
TDM = Time Delay Multiplier (sec)
V = fundamental value of voltage (pu)
F=frequency of voltage signal (pu)
Pickup= volts-per-hertz pickup setpoint (pu)
•
INVERSE CURVE C:
where:
T = operating time
TDM = Time Delay Multiplier (sec)
V = fundamental value of voltage (pu)
F=frequency of voltage signal (pu)
Pickup= volts-per-hertz pickup setpoint (pu)
