Current transformer 1600/5A, class 0.5 TI-1600-5

Current transformers – precise measurements and installation protection

A current transformer with a transformation ratio of 1600/5A is a key element in measurement and protection systems. It is used to safely and accurately convert high primary currents into lower values acceptable by standard meters, counters and protection devices. This device finds application both in industrial installations and in energy consumption monitoring systems.

This model is distinguished by a class of accuracy of 0.5, which guarantees the reliability of measurements even under heavy loads. The construction with a closed core ensures stable operation and minimizes the influence of electromagnetic fields on the surroundings. The transformer is designed for through mounting, which means that the conductor with the measured current is passed through it.

Construction and application

A through-type current transformer with a hole diameter of 46 mm allows current measurement in conductors with a cross-section of up to 32 x 21 mm. The secondary circuit connection is made using a screw connection, which ensures a secure and durable electrical connection. The FS 5 overload factor means that the transformer can temporarily withstand a current five times higher than the nominal value without damage.

The application of current transformers includes:

• Energy consumption measurement: Precise monitoring of power consumption in industrial plants, public buildings and households.
• Installation protection: Detection of overloads and short circuits in electrical circuits, allowing for a quick response and preventing failures.
• Control systems: Providing a signal proportional to the measured current for automation and process control systems.
• Energy quality analysis: Monitoring electrical network parameters, such as harmonic currents, which can negatively affect the operation of devices.

Technical characteristics and benefits

The transformer is characterized by a rated secondary apparent power of 10 VA and a rated secondary current of 5A – standard values ensuring compatibility with most measurement devices available on the market. It should be remembered to follow the manufacturer's recommendation regarding the use of wires with a minimum diameter of 2.5 mm² to connect the secondary winding and grounding the S2 terminal to ensure safety and proper operation of the device. Compliance with IEC 60044-1 confirms compliance with strict requirements regarding safety and measurement accuracy.

It is worth paying attention to a few key advantages:

• High accuracy: Accuracy class 0.5 guarantees reliable measurement results.
• Safety: Insulation withstanding a breakdown voltage of 3 kV/1 min protects against electric shock.
• Durability: Solid construction with a closed core ensures long-lasting and reliable operation of the device.
• Versatility: Wide range of applications in various industries and energy sectors.
• Easy installation: Designed for mounting on a panel or busbar – installation does not require specialized tools or skills.
