CURRENT TRANDUSTER -

A current transducer (or current sensor) is an electrical device that converts current (AC or DC) into a proportional analog signal (typically voltage or current), which can be read by meters, control systems, or monitoring equipment.

1. Wiring Diagram of a Current Transducer (Typical)

Here's a basic diagram and explanation of a 4-wire current transducer setup:

3. Functions of a Current Transducer

Current Measurement: Measures AC or DC current flowing through a conductor.

Isolation: Electrically isolates the measurement system from high current.

Signal Conversion: Converts large current signals to manageable voltage or current outputs.

Monitoring & Protection: Helps in load monitoring, energy metering, and protection systems.

Control: Feeds real-time current data into control systems (like PLCs or controllers).

Would you like a specific type (AC, DC, Hall effect, or Rogowski coil) or a particular brand/model diagram? I can tailor the wiring diagram for your exact use case.

A current transducer works by sensing the electric current flowing through a conductor and converting it into a proportional electrical signal, typically voltage or current, which can be read by control or monitoring systems.

How a Current Transducer Works (Step-by-Step)

1. Sensing the Current

• The current-carrying wire is either passed through a magnetic core (for non-contact sensing) or connected directly (for shunt-based models).
• The flowing current generates a magnetic field, which is detected by the transducer.

2. Magnetic Field Detection

• Inside the transducer, sensors like:
  • Hall Effect sensors (for AC and DC current)
  • Current Transformers (CTs) (for AC current)
  • Shunt resistors (for direct current measurement) detect the strength of the magnetic field or voltage drop.

3. Signal Conversion

• The detected signal is small and is passed to internal signal conditioning circuitry, which:
  • Amplifies the signal
  • Filters noise
  • Converts it to a standard output like:
    • 0–5 V
    • 0–10 V
    • 4–20 mA
    • ±10 V

4. Output to Monitoring System

• The output signal is sent to:
  • A PLC
  • A data logger
  • A microcontroller
  • A display meter
• These devices use the signal for monitoring, controlling, or protection.

Types of Current Transducers and How They Work - 

Example Use Case

If you're monitoring a motor:

• The motor's power line passes through the transducer.
• The transducer senses how much current the motor draws.
• If the current rises abnormally (overload), the transducer sends this info to a controller.
• The controller may trigger a relay to shut down the motor for protection.
