Zero phase current transformers are widely used in circuit leakage current protection such as residual current circuit breakers, leakage current protection switch and so on. When the input line and loop current are not equal, e.g., neutral line is disconnected, power supply for electric energy meter is generated by secondary winding. So, it can achieve the purpose of electricity theft […]

Phase shift (or phase error) and current error (or amplitude error) are critical for electricity measurement accuracy when miniature current transformers are used. For example, when primary current is 5% of rating, the upper limit of phase shift is 8′ for 0.1 class CT, and 4′ for 0.05 class CT. Xianyu’s high-precision current transformers have high linearity over the whole […]

DC immune current transformers are used for circuit where there is direct current (DC), as well as sine alternating current (AC). We provide different encapsulations, from plastic casing to insulation tape wrapping. Due to its compact size, our toroidal current transformer usually have a through-hole big enough for the primary wires in most applications. DC immune current transformers with built-in […]

A miniature current transformer, or mini CT, plays an important role in the current sensing modules or electrical protective devices. It provides safe galvanic seperation in circuit, thus very suitable for applications of high dynamic range. Xianyu’s miniature current transformers have high linearity and low phase error, based on the high permeability nanocrystalline cores. Busbar type miniature current transformers can […]
