Difference Between High, Medium and Low Voltage Transformers
Difference Between High, Medium, and Low Voltage Transformers – A step-down voltage transformer reduces a higher level voltage to a lower level. A step-up voltage … Read more
Transformer
Transformer is the static piece of equipment used for step up and step down the voltage for economic transmission and utilization of electrical power.
In this section we are adding all the technical articles related to transformer like step up transformer, step down transformer, ideal transformer, efficiency and losses, regulation, percentage impedance.
We will also discuss about parallel operation of transformers, copper loss and no load losses and its calculation, all types of routine and type tests, converter duty transformer,dry type transformer, k factor of transformer, maintenance of oil filled and dry type transformer, transformer protection equipment like buccoltz relay, PRD and oil and winding temperature measurement etc.
We will also discuss about the open and short circuit test on transformer.
