A delta-wye transformer is a type of three-phase electric power transformer design that employs delta-connected windings on its primary and wye/star connected windings on its secondary. A neutral wire can be provided on wye output side. It can be a single three-phase transformer, or built from three independent single-phase units.
Loudspeaker with attached step-down transformer for use on a constant-voltage system. Constant-voltage speaker systems refer to networks of loudspeakers which are connected to an audio amplifier using step-up and step-down transformers to simplify impedance calculations and to minimize power loss over the speaker cables.
In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core.
For a step-up transformer, the subscripts in the above equations are reversed where, in this situation, and are greater than and , respectively. As in a two-winding transformer, the ratio of secondary to primary voltages is equal to the ratio of the number of turns of the winding they connect to.
This style of transformer gives an extremely wide bandwidth but only a limited number of impedance ratios (such as 1:1, 1:4, or 1:9) can be achieved with this technique. Choke transformers are sometimes called transmission-line transformers (although see below for a different transformer type with the same name ), or Guanella transformers , or ...
A solid-state transformer can actively regulate voltage and current. Some can convert single-phase power to three-phase power and vice versa. Variations can input or output DC power to reduce the number of conversions, for greater end-to-end efficiency. A Modular Solid-state transformer consists of several high-frequency transformers [1] and is ...
State Republican Executive Committeeman Rolando Garcia said it was a “sad and humiliating way” for Granger to end her 30-year political career, which included being mayor of Fort Worth.
A further transient problem is that with a single coil construction and a star switch, the autotransformer acts as a step-up transformer during the <5 microsecond period at contact separation of the Star point switch. With the motor connected to the 80% voltage tap there will be an escalation of the transient by 5:1 ratio.
