  2. Track lighting - Wikipedia

    en.wikipedia.org/wiki/Track_lighting

    Track lighting is usually combined with directional lamps with reflectors, such as spotlights. [1] These lamps can run under either mains voltage or a lower (often 12 V) voltage. It is common to see line-voltage tracks with low-voltage fixtures. For these, each fixture requires a small built-in transformer to operate it.

  3. Track circuit - Wikipedia

    en.wikipedia.org/wiki/Track_circuit

    One common brand of high-voltage impulse track (HVIT) circuit is made by Jeumont-Schneider. The high voltage penetrates rust and other problems. The HVIT transmits two pulses alternately, a narrow positive one at about 100 V DC and a negative broader one at about 30 V DC. The energy of the two pulses is the same.

    Center-tapped delta transformer Center-tapped delta transformer voltages. High-leg delta service is supplied in one of two ways. One is by a three-phase transformer (or three single-phase transformers), having four wires coming out of the secondary, the three phases, plus a neutral connected as a center-tap on one of the windings.
