A voltage transducer is an electrical sensing device designed to measure AC or DC voltage and convert it into a standardized, proportional output signal such as 0–5V, 0–10V, or 4–20mA. By isolating the measurement circuit from the high-voltage source, a voltage transducer allows safe, accurate, and real-time voltage monitoring in industrial systems, power equipment, and automation control networks. It plays a key role in energy management, system diagnostics, and power quality analysis, where stable voltage data is essential for maintaining operational reliability.
A digital panel meter is an electronic instrument used to display important electrical measurements such as voltage, current, frequency, power, and temperature in a clear numeric format. Its main purpose is to provide accurate and real time readings that help users monitor and control electrical systems more effectively. Digital panel meters are widely used in industrial automation, power systems, laboratory testing, and many types of equipment where reliable measurement is essential. Their popularity has grown due to their precision, easy integration, and ability to present data in a consistent and readable way.
Miniature CTs are essential for reducing high currents to a safe, measurable value, ensuring optimal system performance. In this guide, we’ll discuss the key factors to consider when selecting the perfect CT for your needs. You'll learn about their functions, types, and the best practices for installation.
A Rogowski coil is an electrical device used to measure alternating current (AC) with high accuracy, excellent linearity, and a wide dynamic range. It belongs to the family of non-intrusive current sensors and is commonly used in power monitoring, protection systems, and industrial automation. Unlike conventional current transformers (CTs), a Rogowski coil does not contain magnetic cores. Instead, it is made of a uniformly wound helical coil placed around the conductor being measured. The absence of a magnetic core gives it several advantages, including immunity to core saturation, lightweight structure, and excellent performance in measuring rapidly changing currents.
