Miniature Transformer

A Miniature Transformer is a compact electrical device designed to convert voltage or current levels in low-power applications where space is limited. It includes two main types: the Miniature Current Transformer (CT) and the Miniature Voltage Transformer (VT). The miniature current transformer accurately measures AC current and provides isolated, scaled-down signals for monitoring and protection. The miniature voltage transformer, on the other hand, converts high voltage to a lower, safe level suitable for measurement or control. Both types feature small size, high precision, excellent insulation, and low power loss, making them ideal for smart meters, portable instruments, electronic devices, and industrial control systems. Miniature transformers are widely used in energy management, power monitoring, and automation equipment, where they ensure accurate signal transmission, electrical isolation, and operational safety. Their compact design and reliable performance make them essential components in modern intelligent power and electronic systems.
