Efficiency Improvements by Special Motors

by

Chart showing Efficiency Improvements by Special Motors Power loss area Efficiency improvement 1. Iron  Use of thinner gauge, lower loss core steel reduces eddy current losses. Longer core adds more steel to the design, which reduces losses due to lower operating flux densities. 2. Stator I2R Use of more copper and large conductors increases cross … Read more

Energy Efficient Motors Specialty & Its Constructional Improvement

Intelligent Power Factor Controller (IPFC)

by

Intelligent Power Factor Controller (IPFC) Effects of Low Power Factor  For same kW demand of load, at low power factor current flowing through armature winding of alternator or windings of transformer increases, hence kVA rating required increases.  As current supplied is increases for obtaining proper voltage regulation, conductor size of transmission lines etc. increases. The … Read more

Energy Conservation Opportunities in Transformer

by

Energy Conservation Opportunities in Transformer Q. Energy Conservation Opportunities in Transformer. Opportunities are :  Use amorphous core containing ferromagnetic elements like Iron, Cobalt alloy of high resistivity than silicon steel. So low core losses.  Use encapsulated dry type transformer.  Use autowound (saving in copper) or tapped transformer. Use energy efficient transformer. Use low resistant better … Read more
