Stock of Isolation / Distribution Transformers, Toronto warehouse

An isolation transformer is a transformer, often with symmetrical windings, which is used to decouple two circuits. An isolation transformer allows an AC signal or power to be taken from one device and fed into another without electrically connecting the two circuits. Isolation transformers block transmission of DC signals from one circuit to the other, but allow AC signals to pass. They also block interference caused by ground loops. Distribution transformer is a transformers where electrical energy is passed through to lower high voltage levels on distribution lines down to end-use levels.
Shielded 3 phase isolation transformers have all the feature of the standard 3 phase isolation transformers plus they also incorporate a full metallic shield (usually copper or aluminum) between the 3 phase primary and 3 phase secondary windings. This electrostatic shield ("Faraday Shield") is connected to earth ground and performs two functions: one, it attenuates (filters) voltage transients (voltage spikes). These shielded 3 phase isolation transformers have an attenuation ratio of 100 to 1. Isolation transformers with electrostatic shields are used for power supplies for sensitive equipment such as computers or laboratory instruments.
