A toroidal transformer weighs about half as much as conventional transformer with the same capacity and heat rise. The main materials used in transformer are copper and steel,both of which are getting scarcer with cost increases as a consequence.2. No impregnation is needed to keep the laminates quiet so this potential environmental hazard is avoided.
3. The toroidal transformer fits into a smaller space, which allows chassis plates andenclosures to be smaller with less material used.How to find VA fortoroidal transformers
Volt amps (VA) is the effective power rating for a transformer. In the perfect isolating


transformer, the voltage and current (combined) applied at the primary will exactly equal the voltage and current (combined) on the secondary(s).Efficiency is measure of atoroidal transformer’s ability to delivery the input power to the load. Efficiency is expressed as apercent by:% = ( PO / PI ) X 100 (Where: PO = Output power, PI = Input power, % = Efficiency)
VA Calculation
1.Read thetoroidal transformer’s secondary winding rating (printed or tagged on thetransformer case). This should give a rating such as 5V, 500mA.

Multiply the voltage times the current to receive the VA.

Example: 5V times 500mA (or 0.5A) equals 2.5VA2.Convert the secondary winding VA value to the primary winding VA rating as the equation VA (Primary) equals VA (Secondary) or VA (p) = VA(s)
For example of a 2.5VA secondary, if the primary voltage is 120V the current will be A (p) = VA(s) / V(p). Giving A(p) = 2.5 / 120 = 0.020833 (roughly 21mA).
This is the calculation for a single input winding/single output winding isolating transformer.3.Add the separate VA ratings for atoroidal transformerwith multiple secondary windings.
For secondary winding 1 = 5VA at 500mA
Secondary winding 2 = 24V at 100mA
Total Secondary VA = ( 5 X 0.5 ) + ( 24 X 0.1 ) = 4.9VA
Primary VA will still equal the total secondary VA.
