Retrofitting Allis-Chalmers AIS switchgear | T&D Guardian ... studying the options, we decided on a dual approach: upgrade the tie bus to 2000 amps and replace all of the old 500MVA air breakers with 750MVA vacuum breakers. Although this was technically the best option for upgrading the substation, it required a site-wide electrical shutdown. A shutdown of this size had not been attempted in 25 years.[email protected]
