mini current transformer
A mini current transformer is a compact electrical device designed to measure and monitor alternating current in various electrical systems. These sophisticated instruments accurately convert high-current primary signals into proportionally lower secondary currents, making them essential for measurement and protection applications. The device's core technology utilizes electromagnetic induction principles to provide precise current readings while maintaining electrical isolation between primary and secondary circuits. With their reduced size, typically ranging from 10mm to 50mm in diameter, mini current transformers can be easily installed in confined spaces, making them ideal for modern electrical panels and equipment. They operate across a wide current range, typically from 0.5A to 100A, with exceptional accuracy ratings of up to 0.1 percent. These transformers incorporate advanced magnetic core materials that minimize energy losses and ensure stable performance across varying temperatures and operating conditions. The devices are particularly valuable in energy monitoring systems, smart meters, industrial automation, and power quality analysis equipment, where space constraints and accuracy requirements are critical factors.
