With the Cable Test Facility (CTF) the primary cable can be tested up to 12kV without
opening the cable compartment door. This is done by replacing the integrated earth
connection with the test pins. Disconnecting the earthed connection and access to the test
connections with the test pins is only possible when the breaker is closed in earthed position
(Earthed cable position).
1) Switch the Xiria switchgear to Earthed cable position. See figure 1:

2) Open de CTF front cover plate by removing the padlock (if placed) and turn the front
knobs anti-clockwise. See figure 2:

For safety reasons the CTF front cover plate is earthed with an earth wire. Do not
remove this wire.
3) Release the test connection openings by turning the interlock knob anti-clockwise in
vertical position and insert the test pin(s). See figure 3:
