Window area (Wacal) = Total area (TA) * 1.3įor the above calculated value of tongue width, we choose core number and window area from the core table ensuring that the window area chosen is greater than or equal to the Gross core area. This value is approximate and may have to be modified, depending on the actual winding method.

Extra space required for the former and insulation may be taken as 30% extra space of what is required by the actual winding area.

Total area (TA) = Primary area (pa) + Secondary area (sa)

The total window area required for the core is given by:.

Secondary area(sa)= Secondary turns(n2) / (Secondary turns per sqcm).

Primary area(pa)= Primary turns(n1) / (Primary turns per sqcm).

Then we proceed to calculate as follows:. N2a = Secondary current (Is) calculated / (current density/200)įor these values of primary and secondary currents we choose the corresponding SWG and Turns per sqcm from the wire table. N1a = Primary current (Ip) calculated / (current density/200) So depending on the current densities choosen we now calculate the values of primary and secondary currents that are to searched in wire table for selecting SWG:. It is opted as, the temperature rise for the intermittent operational cases are less for the continuous operational cases. For non-continuous or intermittent mode of operation of transformer one can choose a higher density up to 400A/cm² i.e., twice the normal density to economize the unit cost. The above mentioned wire table is for a continuous rating at current density of 200A/cm². It is the current carrying capacity of a wire per unit cross sectional area.

The width of the tongue of laminations is approximately given by:.

Secondary turns (n2) = Turns per volt(Tpv) * secondary voltage(V2) * 1.03 (Assume that there is 3% drop in transformer windings).

Primary turns (n1) = Turns per volt(Tpv) * Primary voltage(V1).

for ordinary Steel stampings and 1.3Wb/sq cm for CRGO stampings, depending on the type to be used. Manufacturing variations of components should be monitored and controlled.Dimension of Transformer stampings (Core table):įor operation on mains supply, the frequency is 50HZ, while the flux density can be taken as 1Wb/sq cm. In addition, strict control of manufacturing processes is required. All these factors demand greater efforts from researchers and designers for accurate calculation of various stress levels and performance figures for the transformers. Similarly, the guaranteed performance figures and actual test values are now very close. Therefore, the difference between withstand levels (e.g., short circuit, dielectric) and corresponding operating stress levels is diminishing. Also, due to the ever-increasing competition in the global market, there are continual efforts to optimize the material content in transformers.

With the increase in MVA ratings, the weight and size of large transformers approach or exceed transport and manufacturing capability limits. Some of the vital design challenges are: stray loss control, accurate prediction of winding hot spots, short-circuit withstand capability and reliable insulation design.

The increase in current and voltage ratings calls for special design and manufacturing considerations.Īdvanced computational techniques have to be used that should be backed up by experimental verification to ensure quality of design and manufacturing processes. Further, the ongoing trend to go for higher system voltages for transmission increases the voltage rating of transformers.
