  2. Transformer types - Wikipedia

    en.wikipedia.org/wiki/Transformer_types

    A rotary (rotatory) transformer is a specialized transformer that couples electrical signals between two parts that rotate in relation to each other—as an alternative to slip rings, which are prone to wear and contact noise. They are commonly used in helical scan magnetic tape applications.

  7. Voltage transformer - Wikipedia

    en.wikipedia.org/wiki/Voltage_transformer

    A capacitor voltage transformer (CVT), is a transformer used in power systems to step down extra high voltage signals and provide a low voltage signal to the actual VT (voltage transformer) used for operating metering/protective relays due to a lower cost than an electromagnetic PT. The circuit diagram for a simple capacitor voltage transformer

  8. Distribution transformer - Wikipedia

    en.wikipedia.org/wiki/Distribution_transformer

    Transformers designed for below-grade installation can be designed for periodic submersion in water. [14] Distribution transformers may include an off-load tap changer, which slightly adjusts the ratio between primary and secondary voltage to bring the customer's voltage within the desired range on long or heavily loaded lines. [citation needed]

  9. Power system protection - Wikipedia

    en.wikipedia.org/wiki/Power_system_protection

    Power system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults [citation needed] through the disconnection of faulted parts from the rest of the electrical network. The objective of a protection scheme is to keep the power system stable by isolating only the components ...
