DC Current Toroidal Coil 0.0KVrms Hi Pot , Air Core Coil 1GHz High Performance

DC Current Toroidal Coil 0.0KVrms Hi Pot , Air Core Coil 1GHz High Performance

Basic Information

Toroidal coil features an air-cored coil which measures a large current without saturation. As the electro-motive force, however, is differential, it needs to be integrated through electronic circuit to restore waveform and to be an effective value.

Toroidal coil is applied to a current path (secondary conductor) extending from welding transformer to electrode. The coil is coupled with Miyachi Weld Checker for weld quality control, and it is also coupled with welding power supply for feedback control.

Material: Air core

Power: 1Watt~20KWatt

Hi-Pot: 0.0KVrms

Working frequency: 50Hz~1GHz

Working Temperature: -20'C~+125'C

Physics

Toroids are valuable because, like all solenoids, they are inductors. Inductors can induce or cause currents to be created in nearby coils. They were invented in August 1831 by English physicist Michael Faraday. It was Faraday who discovered that a changing magnetic field can induce a voltage in a nearby wire, and this is called Faraday’s Law of Induction. Toroids also have what is known as self-inductance, which is a type of resistance. The toroid resists or fights changes to its own current, whether it is to make it larger or smaller. The strength of the self-inductance depends on the toroid's number of coils and AC source.
