Current Sensors: Enabling Precision and Efficiency in Modern Electrical Systems
As industries accelerate toward automation, electrification, and energy efficiency, current sensors have emerged as vital components in measuring and monitoring electrical current accurately. These sensors are the backbone of modern power systems, electric vehicles, renewable energy infrastructure, and smart devices — ensuring safety, performance, and operational intelligence.
What Is a Current Sensor?
A current sensor is a device designed to detect and convert electric current (AC or DC) into a readable signal that can be measured, analyzed, or processed. The sensor’s output — voltage, current, or digital data — represents the magnitude and direction of the measured current.
Current sensors are broadly classified into two categories:
