the CVT voltage from the
switchgear to the control cubicle:
§Observe the status indication of bushing A1 at the Live/Dead
Indication screen.
§The bushing should display DEAD as the switch is moved to
the "Inject from Inputs" position.
§The bushing will display LIVE when the switch is returned to
the "Connect to Switchgear"
position.The example below shows the display with only Bushing U1/I toggle switch in the "Inject from Inputs" position.

1.7. Loop Automation use of the TTS2
1.7.1. How to exercise Loop Automation
The Voltage Injection Set- TTS2 may be used to exercise Loop Automation on installed, energized or bypassed switchgear.
Refer to Section 20 of the Loop Automation Manual RCLA 6908A for detailed test sequence.
1.8. Interpretation of Measurement Information Displayed.
The tests described in this manual may be conducted using the Centurion System Software (CSS) through the RS232 Port and Serial Cable connection to the Laptop computer (or similar).
The differences in terminology and interpretation of information displayed are shown in the following paragraphs.
CSS – Confirmation of Software.

3§When the switchgear is closed, the voltage injected at SIDE 1 of the TTS2 is represented on both Sides 1&2 (Source and Load) of the Phase Voltage display.
§Therefore, if voltage is injected through SIDE 2 of the TTS2 and the switch is closed, the Phase Voltage representation should be ignored.
§However, note that the Terminal Status display (A1 to B1 etc) always provides true indication of whether the terminals are Live or Dead. Use this display to
confirm the Live/Dead status of terminals.
