TRANSFORMER COMPONENTS AND MAINTENANCE:FORCES AND …machineryequipmentonline.com/electric-equipment/...11/17/2015· A less expensive solution involves servicing the transformer every 3 to 5 years. The amount of moisture in the paper of a transformer is expressed as percent mois- ture by dry weight (%M/dw). The aging factor is controlled by controlling the%M/dw. The upper limit of 0.5 %M/dw should be specified when a transformer is selected.[email protected]
Transformer - Wikipedia transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits.A varying current in any one coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force across any other coils wound around the same core. . Electrical energy can be transferred between ...Get Price
