  • Current-Sense Transformer Application Design Guidelines
    The standard for precise current measurement in instrumentation and other high reliability equipment applications has been the current sense transformer. They are accurate, easy to implement, and reliable under harsh environmental and thermal conditions. In electronic systems applications
  • Current Transformer Measurements
    The Current Transformer (CT) is used to sense AC current in single-phase or three-phase mains circuits. The CT typically has a 1A or 5A AC secondary that connects to a current, power or energy meter. This allows the meter to be located away from the mains wiring. CTs are available in a variety
  • Switch Mode Power Supplies and their Magnetics
    because of its size compared to the others, the Output Inductors, the Input Inductors and the Current Sense Transformer, each with its own important function.
  • Linear Regulated DC Power Supplies
    The universal transformer allows four input voltage ranges - 100/117/220/230-240 VAC ±10%. Before operation at a specific line voltage, the proper input jumpers must be installed. Adequate input fusing is also recommended. For jumpering scheme and fusing requirements, refer to the unit ID label
  • UltraVolt HVPS Output-Current Monitor
    UltraVolt's high-voltage power supplies (HVPSs) have an output-current monitor (Iout Monitor), which allows the total output current of the HV multiplier to be monitored. Note, since the sense circuit is in the return path to the transformer, the current-monitor signal has a sign opposite
  • Using Infrared Techniques for the Condition Assessment of Isolated Phase Bus Duct (.pdf)
    The normal application of isolated phase bus duct is to make the connection between large generators and its associated generator step up transformer. The bus also is used to make connections to auxiliary, reserve auxiliary, potential, and excitation transformers, the purposes of which, are used
  • Ground-fault interrupters
    Ground-fault circuit interrupters (GFCIs), also called earth leakage or residual-current circuit breakers, can sense leakage current to earth ground from live parts and interrupt the circuit automatically when leakage current exceeds a predetermined value. A core-balance protection device serves
