IGDRA5E00100936 is an instrument current transformer (CT) used for:

• Typically integrated in:

  • Industrial drives

  • Power converters

  • Control systems

It converts high primary current → low proportional secondary current for safe measurement.

Operating Principle

• Works on electromagnetic induction:

  • Primary conductor (busbar/cable) passes through CT core

  • Produces magnetic flux

  • Secondary winding generates proportional current

CTs are always connected in series with the load

Typical Technical Features:

• Type: Toroidal / ring-type current transformer

• Measurement type: AC current sensing

• Galvanic isolation between primary and secondary

• High reliability laminated or ferrite core

• Compact encapsulated design (epoxy / resin)

Electrical Characteristics (Typical Range) Primary Side

• Primary current range:

  • Typically tens to hundreds of amperes (depends on application)

• Frequency:

  • 50 / 60 Hz (standard industrial systems)

Secondary Side

• Secondary current:

  • Common values: 1 A or 5 A

• Output type: current (not voltage)

• Burden rating:

  • Typically 2.5 VA – 30 VA (depending on design)

Accuracy

• Typical classes:

  • 0.2 / 0.5 / 1 (metering)

  • 5P / 10P (protection)

Thermal & Environmental Characteristics

• Operating temperature:

  • approx. −25°C to +80°C

• Storage temperature:

  • approx. −40°C to +80°C

• Humidity tolerance: up to 95% (non-condensing)

Insulation & Safety

• High insulation level between primary and secondary

• Designed according to standards such as:

  • IEC 61869-2 (current transformers)

• Isolation voltage: typically several kV

Ensures safe operation in high-voltage environments

Mechanical Characteristics

• Core type: Toroidal (ring type)

• Mounting:

  • PCB mount / panel mount / busbar mount

• Terminals: screw or wire leads

• Encapsulation: resin molded housing

Applications

• Industrial motor drives (VFDs)

• Power converters / inverters

• Switchgear and protection systems

• Energy metering equipment

• UPS systems
