During current transformer manufacture, we reach for high accuracy and low error, while, do you know the Factors Affecting the Current Transformer Error? Here we clarify it in below six points: 1. Current Input The higher current input is, the higher magnetic density of the core proportionally, at same time,  the magnetic permeability ( μ) and the loss angle (ψ) increase,  which reduce t...

Inductors, which also called reactors. In theory, all electrical conductors which can carry current are inductive, because once an electrical conductor is connected to the power, a magnetic field in a certain space it occupies will be created. As we know, while power supply long, or the electrical conductor's inductance is not large enough, the magnetic field is not strong enough. We called induct...

Toroidal transformers are widely used in household equipment & other high technical electronic equipment, here let’s discuss about the basic parameter of the toroidal transformer: 1. Rated power: refers to the maximum load power of the transformer when it is working. It is the output power that the transformer will work for a long time under the specified frequency and voltage without exceedin...

Toroidal transformer are popular application in different field, here let’s discuss details more: Q1: If the toroidal isolation transformer could play as a filtering? A: Can't. The function of transformer is to convert the voltage & the AC current, it can't play as a filtering. Generally, when a transformer is rectified, an electrolytic capacitor will be added to form a rectification filter pa...
