What Is A Split Core Current Transformer (CT)?

A split core current transformer, also known as a clamp-on CT, is a special type of instrument current transformer designed for measuring alternating current without disconnecting the primary conductor. Unlike conventional solid-core CTs, whose iron core forms a closed, unbreakable ring, the magnetic core of a split core CT is cut into two separable halves. Users can open the core, wrap it around an existing cable or busbar, then lock the two core segments together to reconstruct a complete magnetic loop. This unique mechanical structure is its most defining feature.

How Does A Hall Current Sensor Work ？

A Hall current sensor relies on the Hall effect, a fundamental physical phenomenon discovered by Edwin Hall. When a current-carrying conductor sits inside a magnetic field perpendicular to the flow of electric charge, charge carriers inside the conductor experience a sideways force. This force pushes positive and negative charges toward opposite sides of the material, creating a measurable voltage difference called the Hall voltage. Modern Hall current sensors use this principle to detect electric current without direct electrical contact with the measured circuit.

How Does A Miniature Current Transformer Work?

A Miniature Current Transformer (Miniature CT) works by using the principle of electromagnetic induction to measure high alternating currents and convert them into smaller, safer current signals. It is a compact type of instrument transformer that allows electrical systems to monitor current flow while providing electrical isolation between the high-power circuit and measuring equipment.
