This article talks about shielded isolation transformers and their power conditioning qualities (or lack thereof), providing solutions for both.

A method for testing isolation transformers for attenuation is provided in this article, with the requirements being a special (yet simple) test stand arrangement, which includes a signal generator, a standard PC power supply, a shield in/out switch and a handheld oscilloscope.

This article is an in-depth instructional on setting up an isolation transformer with home theater components, and includes a technical diagram and photo for those up to task.

Isolation transformers and galvanic transformers are compared in this article relating to marine and boat use with the functions of isolation transformers in addition to isolation being discussed.

Power and video ground loop isolation is discussed here using two methods, one with an Optical Isolator and the other with an Operational Amplifier.

The Wikipedia article on Isolation Transformers is a very general abstract of information including inner workings, testing, and troubleshooting of isolation transformers. In addition, this article links to other transformer types and other electrical-related articles.

The pros and cons of isolation transformer usage is detailed in this article, including discussing the electrical requirements of IEC 60601-1 as related to medical devices.

This article describes the isolation feature provided by transformers, with technical drawings and raw data, including their purpose, design, and implementation.

Electrical safety regulations throughout the world call for strict isolation between the user and high voltage that can be present if a circuit in the system fails. A transformer is one of the most widely used methods of providing that isolation. However, the emergence of compact, highly efficient switching power supplies, cutting cost, size, weight and cooling requirements, gradually reduced the use of these 50/60-Hz transformers for isolation.

The simple question "Can you explain an isolation transformer?" is answered in this blog post, including information about sheilds and shielding, line frequency transformers, and grounding.

Instructions to build a do-it-yourself audio isolation transformer are presented in this article, complete with technical drawings and explanations.

Signal isolation is needed in power electronics systems that include separate primary and secondary 'grounds'. The feasibility of using a piezoelectric transformer as a galvanic barrier was investigated in this study theoretically and experimentally. The research included the issues of drive, demodulation, bandwidth and common mode rejection. It was found that a small size transformer (2x3mm) could be used effectively to transfer feedback signals from the isolated output of a DC-DC converter to the primary side with a bandwidth of 7kHz when a carrier of 350kHz is used. Wider signal bands can be achieved by applying higher carrier frequencies.
