MANTA TEST SYSTEMS
3.3.13.2 OVERVOLTAGE PICKUP TEST.
To check the pickup level of the 59N element:
1. If you haven’t done so, perform steps 1-4 above (Section 3.3.13.1).
2. Select
Φ
-N/A-N fault mode. If the [MODE/MENU DISPLAY] doesn’t show VOLTS in the upper left
corner, press [VOLTAGE].
3. Press and hold [FAULT], or short the [EXTERNAL START] contact inputs. This holds the MTS-1710
in the fault state, indicated by the illuminated [FAULT] button.
4. Turn the [MODIFY] knob to increase Va (fundamental) until the relay operates. When the relay
contacts close, the [TONE] button will light. If the audible stop trigger tone has been enabled (by
pressing the [TONE] button), the tone also will sound. The voltage may be adjusted, as required, to
determine the pickup level.
5. Release the [FAULT] button, and remove the connections to the [EXTERNAL START] inputs.
3.3.13.3 OVERVOLTAGE TIMING TEST.
To check the operation time:
1. Perform steps 1-2 of the pickup check above.
2. Press and hold [FAULT], and turn the [MODIFY] knob to set the desired overvoltage level.
3. Release the [FAULT] button.
4. Select dynamic operation mode, turn [PREFAULT] on, and press [FAULT] to initiate.
5. When the relay operates, the [STOP/RESET] button will illuminate. Press [TIME] to read the operate
time. Press [TIME] again to toggle between time in seconds/cycles. Press [STOP/RESET] to return to
the prefault state, and to prepare for the next test.
6. For each new value of voltage, select static operation mode, and repeat steps 2-6.
3.3.13.4 3RD HARMONIC UNDERVOLTAGE TEST.
To check the pickup level of the 3rd harmonic undervoltage element:
1. If you haven’t done so, perform the same steps as in Section 3.3.13.1.
2. Select
Φ
-N/A-N fault mode. Press [FREQ], and turn the [MODIFY] knob to select 3rd harmonic.
3. If the [MODE/MENU DISPLAY] doesn’t show VOLTS in the upper left corner, press [VOLTAGE].
4. Press and hold [FAULT], or short the [EXTERNAL START] contact inputs. This holds the MTS-1710
in the fault state, indicated by the illuminated [FAULT] button.
5. Turn the [MODIFY] knob to adjust Va (3rd-harmonic) until the relay operates. When the relay contacts
close, the [TONE] button will light. If the audible stop trigger tone has been enabled (by pressing the
[TONE] button), the tone also will sound. The voltage may be adjusted, as required, to determine the
pickup level.
6. Release the [FAULT] button, and remove the connections to the [EXTERNAL START] inputs.
3.3.13.5 UNDERVOLTAGE INHIBIT TEST.
To check the inhibit of the 3rd-harmonic undervoltage element by the supervising undervoltage element:
