Current Sensor

The Current Sensor is an electronic device used to detect, measure, and monitor electric current in a conductor or circuit. Unlike traditional current transformers that rely on electromagnetic induction, current sensors can use a variety of working principles, including the hall effect sensor and high-precision current transducer.

The working principle depends on the sensor type:
Hall Effect Sensor: When current flows through a conductor, it produces a magnetic field. A Hall element placed near the conductor detects this field and generates a voltage proportional to the current. This method allows both AC and DC measurement.

High-Precision Current Transducer:A High-Precision Current Transducer converts current into a proportional signal using Hall effect or magnetic compensation technology. It features high accuracy, low drift, fast response, and strong electromagnetic immunity. Ideal for precise AC/DC current measurement in power systems, automation, and renewable energy applications.

Current Transformer

A Current Transformer (CT) is an essential device in modern power systems, primarily used to measure and monitor alternating current (AC). Its working principle is based on electromagnetic induction. When the primary winding, often consisting of just one or a few turns, carries the main current, it generates a magnetic field in the magnetic core.

Split Core Current Transformer: Measuring current through magnetic induction with a split-core design that allows easy installation without disconnecting cables. It features high accuracy, easy maintenance, and portability, making it ideal for retrofit projects, energy monitoring, and industrial current measurement applications.

Rogowski Coil: Works on the principle of electromagnetic induction, generating a voltage proportional to the rate of change of current. It features excellent linearity, wide frequency response, no magnetic saturation, and easy installation. Ideal for measuring high or transient currents in power systems and industrial applications.
