3.3.4 Generalized Setup Procedure
The following is a quickstart procedure illustrating the necessary steps required to test fundamental types
of protective relays. For detailed explanations, see Section 4.
Connections:
•
Connect the relay inputs to the appropriate voltage and current outputs.
•
Connect the relay contacts to the [EXTERNAL STOP] trigger contact inputs.
Setup nominal
Φ
-N voltages:
•
Select STATIC operation mode using the [STATIC/DYNAMIC] pushbutton.
•
Turn [FAULT TYPE] to
Φ
-N mode.
•
Press [PREFAULT] on.
•
Press [VOLTAGE] to display the
Φ
-N voltage.
•
For each of the A-N, B-N and C-N selections on the [FAULT PHASE] selector, adjust the voltage to the
desired nominal (prefault)
Φ
-N voltage
.
Setup desired fault mode and current mode:
•
Select the desired fault mode on the FAULT MODE selectors.
•
Select the desired current mode on the [CURRENT MODE] selector. (Most single phase testing
requires the I1-LOW mode).
Setup desired fault current and voltage:
•
Press [CURRENT].
•
Press and hold the [FAULT] button to apply fault values of current and voltage.
•
While holding in the [FAULT] button, adjust the current to desired fault values.
•
Press [VOLTAGE].
•
While holding in the [FAULT] button, adjust the voltage to desired fault values.
•
When the relay operates, the [TONE] button will light. Press the [TONE] button to enable/disable the
audible contact sense tone.
Setup desired phase between voltage and current:
•
Press [PHASE].
The phase angle displayed will be the phase between the selected voltage (see lower left corner of the
[MODE/MENU DISPLAY]), and the current. The display reads voltage leading current. Note that a
minimum voltage and current output must be present to display a phase reading.
•
Turn the [MODIFY] knob to adjust the phase angle. The phase angle between the current and all three
voltages changes when this adjustment is performed.
