  2. Polarity (mutual inductance) - Wikipedia

    en.wikipedia.org/wiki/Polarity_(mutual_inductance)

    In the "subtractive" arrangement, the H1 and X1 terminals are adjacent, and the voltage measured between H2 and X2 would be the difference of the high voltage and low voltage windings. [3] Pole mounted distribution transformers are manufactured with additive polarity, while instrument transformers are made with subtractive polarity.

  3. Transformer types - Wikipedia

    en.wikipedia.org/wiki/Transformer_types

    A leakage transformer, also called a stray-field transformer, has a significantly higher leakage inductance than other transformers, sometimes increased by a magnetic bypass or shunt in its core between primary and secondary, which is sometimes adjustable with a set screw. This provides a transformer with an inherent current limitation due to ...

    en.wikipedia.org/wiki/BMW_X1_(U11)

    The third generation of the BMW X1 consists of the U11 (short wheelbase) and the U12 (long wheelbase) subcompact luxury crossover SUVs.Continuing in the way of the previous generation, this model is based on the modular UKL2 platform, which categorises compact, front-wheel drive based vehicles such as the 2 Series Active Tourer multi-purpose vehicle and the Mini Countryman crossover SUV.

    A revision (codenamed "Mariko") with greater power efficiency, known officially as Tegra X1+ was released in 2019, [102] fixing the Fusée Gelée exploit. It's also known as T214 and T210B01. It's also known as T214 and T210B01.

  6. Current transformer - Wikipedia

    en.wikipedia.org/wiki/Current_transformer

    A current transformer has a primary winding, a core, and a secondary winding, although some transformers use an air core. While the physical principles are the same, the details of a "current" transformer compared with a "voltage" transformer will differ owing to different requirements of the application.

    en.wikipedia.org/wiki/APMonitor

    Advanced process monitor (APMonitor) is a modeling language for differential algebraic equations. [1] It is a free web-service or local server for solving representations of physical systems in the form of implicit DAE models.

  9. Quarter-wave impedance transformer - Wikipedia

    en.wikipedia.org/wiki/Quarter-wave_impedance...

    The quarter wave transformer is an alternative to a stub; but, whereas a stub is terminated in a short (or open) circuit and the length is chosen so as to produce the required impedance transformation, the λ/4 transformer is in series with the load and its length and characteristic impedance are designed to produce the required impedance ...
