  • CURRENT & VOLTAGE (POTENTIAL) TRANSFORMERS Glossary
    transformer rated 4200:120, the ratio is 4200:120 or 35:1. Transformer Ratio - (TR) - Total ratio of current and voltage transformers. For a 200:5 C.T. and 480:120 P.T., TR = 40 X 4 = 160. Weatherability - Transformers are rated as indoor or outdoor, depending on construction (including hardware). Accuracy
  • Donut Transformers
    Donut transformers, also called toroidal transformers, have no internal primary winding as such. The primary is the conductor in which the current is to be monitored, and is not an integral part of the transformer. The primary conductor is simply placed through the window of the current transformer
  • Current Transformers
    Current transformers (CT's) provide a simple, inexpensive and yet accurate means of sensing current flow in power conductors. They are available in 3 basic configurations: Split Core CT's are available for measuring currents from 100 to 5000 amps, with windows in varying sizes from 1" by 2" to 13
  • Wound Primary Current Transformers
    Wound primary current transformers have primary windings that usually consist of more that one turn. Wound primary transformers have an internal primary winding and have no windows for the primary conductor to pass through. They have an advantage in that the designer can make units with low current
  • Information Related to Eddy Current Inspection of Machined Parts
    Hughes (1830­1900), an American. inventor who discovered that a coil of wire carrying an alternating current was affected by any. conductive material coming near it. This effect related directly to the eddy currents created in the. conductive material by the "transformer effect" of the alternating
  • Bar Transformers
    Bar transformers (bar current transformers) are toroidal transformers with a bus bar permanently inserted through the window of the toroid. The bus bar serves as the primary conductor. Bar transformers are inserted directly into the circuit which they will be used to monitor. It is a common error
