  • Abstract
    Metal-clad SWITCHGEAR using magnetic-type power circuit breakers has had a top limit of 500 mva (megavolt-amperes) interrupting capacity for some time. However, studies begun in the early 1950´s indicated that the loads to be expected in the foreseeable future required area substations with mva ratings about 50 to 65% larger than those obtainable with the 13.8-kv 500-mva breaker equipment. A 750-mva equipment will permit an increase in substation size within this range.
