The 1A current clamp meter, also known as the 1A clamp-on ammeter, is a versatile and invaluable tool used for a variety of electrical applications. This instrument is specifically designed to measure low currents in electrical circuits with precision and accuracy. The 1A current clamp meter offers several specific uses in different electrical and electronic applications.

OSWELL will present at the INA PAACE Automechanika in Mexico and the FIEE in Brazil in July.

A current clamp mainly consists of a jaw, a circuit board, a digital display screen, and operating buttons. The jaw is the core component of the current clamp, typically made of ferromagnetic materials with a pair of electromagnets inside to detect current signals and convert them into voltage signals. The digital display screen is used to display the measured current value, and the operating buttons are used to set parameters and switch between function modes.

A rogowski coil is a circular coil evenly wound around a non-ferromagnetic material. The output signal is the derivative of the current with respect to time. Through a circuit integrating the output voltage signal, the input current can be truly restored. The coil has the characteristics of real-time current measurement, fast response speed, no saturation, suitable for AC, especially high frequency current measurement.

As the complexity and scale of modern power systems continue to expand, the demand for on-site testing and rapid diagnostics has grown significantly. Whether it’s routine inspections of substations, commissioning of new renewable energy installations, or troubleshooting in industrial facilities, technicians require measurement tools that are easy to carry, quick to deploy, and capable of operating in confined or challenging environments. In response, portability and miniaturization have emerged as defining trends in current clamp design, with innovative products like the SDQxxX series current clamps and 60A CTs with mini magnetic shielding ring structures leading the way. These advancements are not only enhancing operational efficiency but also redefining how electrical measurements are performed in the field.

In the era of digital transformation, traditional current clamps—once merely tools for basic electrical current measurement—are evolving into intelligent monitoring terminals through the integration of Internet of Things (IoT) and Artificial Intelligence (AI) technologies. Modern smart current clamps are no longer limited to simple data acquisition; they now enable remote monitoring, predictive analytics, and automated diagnostics, revolutionizing how electrical systems are managed and maintained.

Current clamp is a versatile and high-precision current measurement device designed for a wide range of electrical and industrial applications. With a primary current range of 1A to 1250A and a rated secondary output of 0A to 5A (or 0~1V), this series meets accuracy grades of 0.5 and 1, complying with GB/T 20840.1 and 2.0 standards. Its robust design and reliable performance make it indispensable in power monitoring, energy management, industrial automation, and electrical protection systems.
