The phase selection logic also provides the information about the phase specific fault
directions. The STR DIRPHSA, STR DIRPHSB and STR DIRPHSC outputs
indicates the direction of the fault in phase A, B and C respectively. The general fault
direction information is provided by the STR DIRGENERAL output. The information
is available over GOOSE communication.
Timer
Once the Timer is activated, it activates the START output. The STR PHSA, STR
PHSB and STR PHSC outputs indicate which phases are started. The time
characteristic is according to the definite time. When the operation timer has reached
the value set by Operate delay time, the OP GENERAL output is activated. The OP
PHSA, OP PHSB and OP PHSC outputs indicate which phases are operated. If the
fault disappears before the module operates, the reset is instantaneous and STR
GENERAL output is deactivated.
When Directional mode is set to "Non-directional", outputs OpFwd and OpRev are
activated when a fault is detected in the "Forward" or "Reverse" direction
respectively. However, these outputs are also available when Directional mode is set
to "Forward" or "Reverse".
When Directional mode is set to "Non-directional" and PHPTOC
operates in unknown direction, none of the LEDs show fault
inditation.
The OP GENERAL output is available at LED 6 of SIM8F module.
The phase segregated as well as general start and operate outputs STR GENERAL,
STR PHSA, STR PHSB, STR PHSC, OP GENERAL, OP PHSA, OP PHSB, OP
PHSB, OpFwd and OpRev are available over communication.
Directional overcurrent characteristics
The forward and reverse sectors are defined separately. The forward operation area is
limited with the Min forward angle and Max forward angle settings. The reverse
operation area is limited with the Min reverse angle and Max reverse angle settings.
The sector limits are always defined as positive degree values.
In the forward operation area, the Max forward angle setting defines the
counterclockwise sector and the Min forward angle setting defines the corresponding
clockwise sector, measured from the Characteristic angle setting.
In the backward operation area, the Max reverse angle setting defines the
counterclockwise sector and the Min reverse angle setting defines the corresponding
clockwise sector, measured from the Characteristic angle setting set to 180°.
