  • DETERMINING BURDEN FOR CURRENT TRANSFORMERS
    DETERMINING BURDEN FOR CURRENT TRANSFORMERS. CT Burden Chart. DETERMINING BURDEN FOR CURRENT TRANSFORMERS. CT SECONDARY WIRE SIZING EXAMPLE. A Watt Transducer (0.75 VA burden) is to be used with three 1200:5 current transformers. The CT secondary is 30 ft. one way. To maintain the maximum CT
  • 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

  • Application Note: Transformer Selection Considerations
    the continuous power when sizing the transformer for a servo system application that requires peak torque at high speed. Transformers are not ideal, as the load current from the transformer increases; the output voltage will drop. From earlier discussions, the voltage supplied to the servo drive is one
