Old switchgear revamp

Did anyone had experience with old model switchgear revamp work.

Only control wiring.

No power components change.

  • How old and what sort of switchgear? Approaches and techniques can differ depending on the details.

  • Please elaborate your query bit details. What kind of technical issue you are facing or what details / solution you are expecting in old SWGR revamp scope? 

  • I think this needs to be clarified. If you mean changing protection relays for example, i had such a chance in the past with an old Toshiba switchgear that had electromechanical relays, as part of a project we had to change them with new IED relays, however this required major engineering and change in the control circuit schematics.
