  2. Litz wire - Wikipedia

    en.wikipedia.org/wiki/Litz_wire

    Litz wire is a particular type of multistrand wire or cable used in electronics to carry alternating current (AC) at radio frequencies. The wire is designed to reduce the skin effect and proximity effect losses in conductors used at frequencies up to about 1 MHz .

  3. VLF cable testing - Wikipedia

    en.wikipedia.org/wiki/VLF_cable_testing

    Frequency ranges used are within the range of 0.01 Hz to 0.1 Hz, where frequency selection depends on the load presented by the cable. Test voltage levels are either calculated using a multiple of the cable's nominal phase-phase voltage or via tables in IEEE 400.2; typically they are in the range of 1.5 U0 to 3 U0.

    ZVA40 vector network analyzer from Rohde & Schwarz.. A network analyzer is an instrument that measures the network parameters of electrical networks.Today, network analyzers commonly measure s–parameters because reflection and transmission of electrical networks are easy to measure at high frequencies, but there are other network parameter sets such as y-parameters, z-parameters, and h ...

    The male contact was designed to be the same size as the cable conductor so that it could be used as the mating pin for optimized VSWR. Common applications included Mil-Aero, telecommunications, RFID, antennas, test and measurement and radar systems. SMZ connector – System 43 (BT43 and High Density HD43) for use in DDF. This is a 75 ohm ...
