transformer loss

transformer loss

[tranz′fȯr·mər ‚lȯs]
(electricity)
Ratio of the signal power that an ideal transformer of the same impedance ratio would deliver to the load impedance, to the signal power that the actual transformer delivers to the load impedance; this ratio is usually expressed in decibels.

Considering the transformer loss, it is a aperiodic component and decays with time.
In this case, a 250:50 [ohms] impedance transformer is required for each output port and an extra measurement is required to measure the transformer loss for each output port in addition to the port's insertion loss/gain measurement.
Reference [3] used a standardized engineering approach according to IEEE Standard C5791 [4] to preliminarily assess the impact of increased ambient temperature on transformer loss of life at five locations in the USA.
Optimization of transformer design for high efficiency and high-power density converter is subjected to the reduction of overall transformer losses. These losses are composed from losses in windings and losses in transformer core (hysteresis losses, eddy currents).
Thus, the value engineered solution with 13.8kV/60Hz again saved not only the initial cost by the elimination of transformers, but also operating cost was saved by avoiding 2 to 3 per cent transformer losses.
For example, accounting for transformer losses, a 15-kVA AC source will require a 17-kVA three-phase input transformer weighing approximately 140 lb.
