Üç Fazlı Devreler
In general, AC power distribution systems are classified as single-phase, two-phase, or three-phase.
Single-phase circuits involve a single source ...
Üç Fazlı Gerilim Üretimi
A three-phase AC generator with a rotating magnet surrounded by stationary windings is used to generate three-phase voltages.
The stator houses three ...
Üç Fazlı Gerilimler
In three-phase four-wire systems, three Y-connected voltage sources generate balanced phase voltages.
There are two phase sequences based on the order in ...
Yıldız-Yıldız (Y-Y) Devresi
Balanced four-wire Y-to-Y systems consist of three balanced Y-connected sinusoidal voltage sources and loads with the neutral wire connecting both the ...
Yıldız-Üçgen (Y-Δ) Devresi
In electrical power grids, balanced Y-to-Delta circuits feature Y-connected voltage sources and delta-connected loads, typically without a neutral line.
...
Üçgen-Üçgen (Δ-Δ) Devresi
A balanced delta-to-delta system has a delta-connected source and load.
The delta-connected sources are assumed to be in positive sequence to express the ...
Üçgen-Yıldız (Δ-Y) Devresi
A balanced delta-to-Y system features a balanced delta-connected source powering a balanced Y-connected load.
In this delta-Y circuit, a positive abc ...
Üç Fazlı Devrede Güç

To determine the instantaneous ...
Üç Fazlı ve Tek Fazlı Devrelerde Güç Dağılımı
Consider a two-wire single-phase system providing electricity to homes and a three-wire balanced three-phase system powering a factory with heavy ...
İletim Hattındaki Kayıp
Consider a balanced three-wire Y-to-Y circuit represented in the time domain, which can be transformed into a per-phase equivalent circuit.
First, the ...
Hat Kaybını Azaltma
To minimize line losses in three-phase circuits, two transformers are added: a step-up transformer at the source and a step-down transformer at the load.
...
