2. Distribution transformer - Wikipedia

   en.wikipedia.org/wiki/Distribution_transformer

   Primaries provide power at the standard distribution voltages used in the area; these range from as low as 2.3 kV to about 35 kV depending on local distribution practice and standards, often 11 kV (50 Hz systems) and 13.8 kV (60 Hz systems) are used, but many other voltages are standard.

4. Load profile - Wikipedia

   en.wikipedia.org/wiki/Load_Profile

   The power transformer or battery-to-grid are critical aspects of power distribution and sizing and modelling of batteries or transformers depends on the load profile. [1] The factory specification of transformers for the optimization of load losses versus no-load losses is dependent directly on the characteristics of the load profile that the ...

5. Split-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Split-phase_electric_power

   The phase shift in Europe is 120°, as is the case with three-phase current. That is why we calculate 130 V × √ 3 = 225 V. A three-phase final step-down transformer is then used. One house gets phases A and B, the next house gets phase B and C, the third house gets phase A and C.

6. Current transformer - Wikipedia

   en.wikipedia.org/wiki/Current_transformer

   Basic operation of current transformer SF 6 110 kV current transformer TGFM series, Russia Current transformers used in metering equipment for three-phase 400-ampere electricity supply. A current transformer has a primary winding, a core, and a secondary winding, although some transformers use an air core.

7. Per-unit system - Wikipedia

   en.wikipedia.org/wiki/Per-unit_system

   In the power systems analysis field of electrical engineering, a per-unit system is the expression of system quantities as fractions of a defined base unit quantity. . Calculations are simplified because quantities expressed as per-unit do not change when they are referred from one side of a transformer to t

9. Delta-wye transformer - Wikipedia

   en.wikipedia.org/wiki/Delta-wye_transformer

   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.
