CHAPTER 6: SETPOINTS

S3 PROTECTION

350 FEEDER PROTECTION SYSTEM – INSTRUCTION MANUAL

6–95

Wattmetric ground fault (32N)

The Wattmetric ground fault element, also called Wattmetric Zero-sequence Directional 
element, responds to power derived from zero-sequence voltage and zero-sequence 
current in a direction specified by the element characteristic angle. The angle can be set 
within all four quadrants, so the measured power can be active or reactive or some 
combination thereof. Therefore the element can be used to sense either forward or reverse 
ground faults in either inductively, capacitively, or resistively grounded networks. The 
inverse time characteristic allows time coordination of elements across the network.
Typical applications include ground fault protection in solidly grounded, ungrounded, 
resistor-grounded, or resonant-grounded networks, or for directionalizing other non-
directional ground elements.
The following path is available using the keypad. For instructions on how to use the 
keypad, please refer to

SETPOINTS > S3 PROTECTION > SETPOINT GROUP 1(2) > WATT GND FLT

FUNCTION

Range: Disabled, Alarm, Latched Alarm, Trip, Control
Default: Disabled

For details see 

Common setpoints

.

VOLTAGE

Range: Calculated Vn, Measured Vx 
Default: Calculated Vn

This setting uses neutral voltage (that is, three times the zero-sequence voltage). The 
setpoint allows selecting the internally calculated neutral voltage, or externally supplied 
voltage (broken delta VT connected to the auxiliary channel of the relay).

NOTE

NOTE: 

When Calculated Vn is selected, the VT CONNECTION setting must be set to wye for the 
element to run. When Measured Vx is selected, the AUX VT INPUT under 

SETPOINTS > S2 

SYSTEM SETUP > VOLTAGE SENSING

 must be set to neutral voltage (Vn) under the VT bank 

setpoints for the element to run. 

VOLTAGE PICKUP

Range: 0.02 to 1.00 x VT in steps of 0.01 x VT
Default: 0.20 x VT

This setpoint specifies the minimum neutral voltage for supervising the power 
measurement. This threshold is higher than possible unbalance during normal operation 
of the system. Typically, this setpoint is selected at 0.1 to 0.2 x VT for ungrounded or 
resonant grounded systems, and at 0.05 to 0.1 x VT for resistor grounded systems. 
When the VOLTAGE setpoint value is Measured Vx, 1 x VT is the AUX VT SECONDARY 
setpoint value multiplied by the AUX VT RATIO setpoint value.
When the VOLTAGE setpoint value is Calculated Vn, 1 x VT is the VT SECONDARY setpoint 
value multiplied by the VT RATIO setpoint value.

CURRENT

Range: Calculated In, Measured Ig
Default: Calculated In

This setting corresponds to the neutral current (that is, three times the zero-sequence 
current), either calculated internally from the phase currents or supplied externally via 
the ground CT input from more accurate sources such as a core balance CT. This 
setpoint selects the source of the operating current.
