The Fundamentals of Automatic Voltage Regulation
Electrical voltage is not always stable Today’s electrical power grid is a complex and evolving system. New residential and commercial developments put increasing strain on the system at the very same time as the number of electronic devices we use grows daily. In addition, many older residences are being rebuilt and upgraded with much larger power demands that are outpacing the development of...
Understanding the Torus Power isolation transformer
Let’s start with power demand and quality… The electrical load in a home today is much different than it was for past generations. Today’s homes have so many more devices to power like computers and printers, chargers for wireless devices, modems, routers and home networking devices, telephones, televisions and cable boxes, dimmers and lights (low voltage, LED, incandescent and fluorescent),...
How to Define ‘Clean Power’ Systems
Industry veteran Arthur Kelm explores the definition of clean power, including motor loads, sensitive electronic loads, and lighting and convenience loads. After working over 43 years in the professional recording industry and the past 12 years of that involved in the high end A/V market, I have lost track of the number of times I have heard the term “clean power” used to describe someone’s...
NBT for the Rest of Us
NBT technology is a proprietary noise filtering technology that eliminates the need for external filters, such as capacitors, and other components that can fail over time. Using NBT filtering technology, Torus Power toroidal transformers carefully balance the inherent inductance, capacitance, and resistance characteristics, enabling the transformer to act as a highly effective low-pass filter....
Power Conditioning vs. Power Isolation
By Ross Whitney – Technical Sales and Support for Torus Power Look through any high-end AV dealer's showroom or website for power conditioning equipment and you will find a number of approaches. Some power conditioners are equipped with protection for phone, cable TV and satellite lines. Many units offer surge suppression. Some units offer battery backup or UPS capabilities. Others provide...
Three Myths about Power Management
By Ross Whitney – Technical Sales and Support for Torus Power There are many myths about electrical power and how it can affect audio and video systems. Today we will look at three of the most pervasive myths. The first myth is the most important one because if you believe it and follow it you could die. People who ought to know better (but don't) position themselves as experts, on the Internet...
Why use an isolation transformer?
Why use an isolation transformer? What makes an isolation transformer different and better? A combination of artful engineering and precision manufacturing allows every Torus Power transformer to achieve an unmatched level of electrical isolation, operating as an electronic firewall and separating your sensitive electronic equipment from electrical impurities carried by the power grid while...
