5 Description
5.1 The Schneider T200E and Lucy Gemini 2 are control units/RTUs that are used to
provide local and remote control of secondary switchgear. A description of these
units is given in Appendix A.
5.2 New switchgear ordered with remote control will generally be supplied and
delivered to site with the remote control already fitted. The list below shows some of
the most popular configurations:
 RN2c – remote control on ring switch 1, FPI fitted to ring switch 1.
 RN6c – remote control on ring switch 1 and circuit-breaker, FPI fitted to ring
switch 1.
 RE2c/SE6 – remote control on ring switch 1, ring switch 2 and SE6, FPI fitted to
ring switch 1, ring switch 2 and SE6.
 RE2c/CE2 – remote control on ring switch 1, FPI fitted to ring switch 1 and ring
switch 2.
 CE6 – remote control on circuit-breaker.
 VRN2a – remote control on ring switch 1, FPI fitted to ring switch 1.
 VRE2a/SSE – remote control on ring switch 1 and SSE, FPI fitted to ring switch
1, ring switch 2 and the SSE.
However on occasions it will be necessary to revise the as delivered arrangement,
typically to facilitate mounting of the control unit onto the substation wall or a free
standing frame, or to provide remote control for additional equipment installed later
on site.
A number of additional components are required to carry out these tasks which are
listed in Appendix E of this document for easy reference.
