  • 12 different parts of a transformer | Transformer parts

    Transformer facilitates the delivery of power electric energy at minimum power loss. The basic parts of a transformer are core, the primary winding and secondary winding. Apart from these, there are various other components such as insulation, transformer oil, cooling arrangements, protection relays, enclosure etc present in larger transformers.

  • CHAPTER Winding your own coils

    If you make an RF/IF transformer, then there will be two windings. Try to sepa-rate the primary and secondary windings if both are tuned. If one winding is not tuned, then simply wind it over the “cold” (i.e., ground) end of the tuned winding— no separation is needed.

  • Transformer Turns Ratio (TTR) Testers - ATEC

    Transformer turns ratio (TTR) testers are designed to perform TTR testing. TTR testers are able to verify the operating principle of a power transformer, and identify any shorted turns or open-circuited conditions. With a low voltage AC test, transformer turns ratio equipment measures the ratio of high voltage to all other winding at no-load.
