Despite its outstanding qualities as an gaseous electrical insulator, it had initially no practical use in engineering. It was only by the end of the 1950s, first in the USA and soon afterwards in Europe that this particular gas was more extensively explored, leading to its principle application as an extinguishing and electrical insulating medium. Commonly used in power applications, Sulfr hexafluorideis used in high-voltage circuit breakers, metal-enclosed switchgear, linear accelerators, high-voltage transformers, capacitors and gas insulated lines worldwide.Get price

Buy Transformers - Distrelec Switzerland

A transformer is a passive electrical device that is used to transfer electrical energy from one circuit to another, or to multiple circuits. This is achieved through changing the magnetic field: a varying current in one transformer coil produces a varying magnetic flux which then induces a varying electromotive force across any other coils wound around the same core.Get price

Isolation transformer - Wikipedia

An isolation transformer is a transformer used to transfer electrical power from a source of alternating current power to some equipment or device while isolating the powered device from the power source, usually for safety reasons. Isolation transformers provide galvanic isolation; no conductive path is present between source and load. This isolation is used to protect against electric shock, to suppress electrical noise in sensitive devices, or to transfer power between two circuits which mustGet price
