3-Phase Power Solutions Isolation Transformers
An isolation transformer is a transformer with separate primary and secondary windings. These windings are typically separated with a sheet of nonmagnetic conducting material, usually copper or aluminum, connected to ground, which acts as a shield to prevent the noise of one system from affecting another. Reduction of noise prevents data disruption in digital electronic equipment. Isolation 3-phase transformers also reduce the harmonic currents fed back to the source by nonlinear loads because balanced, 3-phase harmonic currents will cancel each other out in the delta windings of the transformer. Three-phase isolation transformers reduce harmonic distortion by eliminating the triplen harmonics. A reduction in harmonic distortion improves the power and reduces the harmonic effect on other loads. Isolation transformers are constructed with two isolated faraday shields between the primary and secondary windings. When it is properly installed, the shield, which is closest to the primary winding, is connected to the common power supply ground. The shield closest to the secondary winding is connected to the shield of the circuit to be isolated. Using the two shields diverts high frequency noise. |
Remember, when making a decision about buying any transformers, make sure the manufacturer offers high quality, efficient transformers manufactured to your specifications. We recommend Hammond Transformers, because they have been in business for 91 years and know the state-of-the-art technology of transformers.
