The D36N current transformer from Chauvin Arnoux is a measuring instrument for the accurate detection of alternating currents in industrial and technical installations. It is specifically designed for measuring medium and high currents on thick cables as well as on busbars. The rectangular shape of the jaw allows for secure and precise encirclement of conductors with a cross-section of up to 64 x 150 mm. The device is designed for use in electrical installations with a voltage category of 600 V CAT III, ensuring safe measurement in industrial environments.

Current transformer with rectangular shape and turns ratio 3000/3 enables the conversion of high primary currents into a measurable secondary signal. The measurement range covers currents from 1 A to 3600 A AC, with the nominal current rating at 2400 A AC. The typical accuracy is ≤ 0.5 %, ensuring high measurement accuracy for applications in energy and process monitoring. The low phase shift makes the device suitable for power measurements where the phase relationship between voltage and current is important.

Technology explained clearly: The current transformer operates on the principle of a transformer. The current to be measured flows through the jaw, generating a magnetic field in the magnetic circuit. This induces a proportional alternating current signal in the secondary circuit, which can be tapped via the output sockets. The distributed windings and the quality of the magnetic circuits ensure stable and reproducible signal transmission, even at high currents.

Compatibility and accessories: The device is equipped with insulated sockets (Ø 4 mm), suitable for connecting to measuring instruments such as multimeters, current clamps, or data loggers. An integrated overvoltage protection at the output protects connected devices from transient voltage spikes. Suitable accessories include a set of two adapters BNC socket/4mm plug, enabling connection to devices with BNC connectors.

Mounting and installation: The jaw is simply placed around the conductor to be measured, with the rectangular shape ensuring secure encirclement even for irregular cross-sections. No additional mounting aids or tools are required. Installation is carried out without interrupting the current flow, allowing plant operation during measurement.

Advantages in operation: The high accuracy, low phase shift, and robust construction make the D36N a reliable tool for electrical measurement. The combination of rectangular shape and overvoltage protection increases safety and applicability in complex electrical systems. The device is designed for use in industrial environments where high currents and mechanical stresses are common.
