In modern electrical systems, accurate measurement and reliable monitoring of current are critical for safety, efficiency, and equipment longevity. CT transformers (Current Transformer transformers) are essential components that provide precise current measurement, enabling effective power management and system protection. Tianrui, a leading manufacturer of high-quality electrical...

As the global shift toward renewable energy accelerates, energy storage systems (ESS) have become essential for balancing supply and demand, stabilizing grids, and supporting electric mobility. These systems—ranging from residential battery packs to utility-scale installations—require robust protection mechanisms to ensure safety and reliability. One of the most critical yet often...

Accurate current measurement is one of the foundations of modern electrical engineering. From power distribution grids to industrial automation and energy-monitoring systems, understanding real-time current flow is essential for protection, control, and billing. Among the various sensing technologies developed for this purpose, the CT transformer—also known as the current...
