  • 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

  • Determining Burden For Current Transformers
    If a Current Transformer (CT) reads low, then the secondary is probably overloaded. Burden is the load which may be imposed on a transformer secondary by cables and connected devices without causing an error greater than the stated accuracy classification. Lower burden and proper sizing can improve
  • Electric Current Abroad
    To assist U.S. manufacturers, exporters and individuals living or traveling abroad, these pages list the characteristics of electric current available and the type of attachment plugs used in most countries. These pages are based on a handbook published in 1998 by the U.S Department of Commerce

  • 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
