What is the difference between Power Transformers and Distribution Transformers?

Primary Contrast between Power Transformer and Appropriation Transformer 

In short, those transformers introduced at the consummation or accepting purpose of long and high voltage transmission lines are the power transformers (for the most part Advance up). At the other hand, The circulation transformers (by and large shaft mounted) are those introduced close-by the heap terminals (City and towns) to give usage voltage at the buyer terminals (for the most part venture down). distinction between Power Transformer and Conveyance Transformer

Below are some additional differences between power and distribution transformers.

• Power transformers are utilized as a part of transmission system of higher voltages for advance up and advance down application (400 kV, 200 kV, 110 kV, 66 kV, 33kV) and are by and large evaluated over 200MVA. 

• Dispersion transformers are utilized for bring down voltage dissemination arranges as a way to end client network. (11kV, 6.6 kV, 3.3 kV, 440V, 230V) and are by and large appraised under 200 MVA. 

• A power transformer more often than not has one essential and one optional and also one info and yield setup. A dissemination transformer may have one essential and one partitioned or "Tapped" auxiliary, or at least two secondaries. 

• Power transformers by and large work at about full – stack. Be that as it may, an appropriation transformer works at light loads amid real parts of the day. 

• The execution of the power transformers is by and large dissected by business or most extreme proficiency since they are intended for greatest productivity at full load. While, the execution of an appropriation transformer is judged by throughout the day effectiveness of transformer since they are intended to be worked for most extreme productivity at 60-70% load as they are ordinarily doesn't work at full load all the day as there are crest hours for stack in 24 hrs which are not same without a moment's delay constantly. 

• The rating of a high transformer is ordinarily more noteworthy than that of conveyance transformer. 

• In Power Transformer, the motion thickness is higher than the dissemination transformer. 

• Power transformers, essential twisting constantly associated in star and optional twisting in delta associations while in conveyance transformers, essential twisting associated in delta and auxiliary in star association. read more about the correlation between star and delta associations. 

• In The Sub station, toward the finish of the transmission line, The power transformer association is in Star-Delta.(to venture down the level of voltage) 

• Toward the start of the transmission line (H-T), the association of the power Transformer is in Delta – Star (to venture up the level of voltage). Likewise, not that a similar association i.e Delta – Star association is utilized as a part of three stage venture down conveyance transformer also
