While most transfer switches are equipped with basic features that make them suitable for simple installations, larger or more complex projects often require additional features to meet special requirements. One such special requirement is the need to protect sensitive equipment whenever building loads are switched between two live, un-synchronized, power sources. How exactly does a proposed transfer switch execute a transfer between the normal source and the emergency source, and what effect will the transfer sequence have on the connected loads? Learn the key differences between open, delayed and closed-transition automatic transfer switches, and how to specify the right equipment.
New emission regulations have led to massive changes in the way diesel engines are cooled. Older engines had a single jacket water circuit (using a mixture of ethylene glycol and water) that was responsible for removing heat from the engine and transporting it to a radiator. Simple enough, right? Fast forward to today! Engines are … Read more
Typical of any industry, the power generation industry is filled with acronyms and technical terms. Some of them are referenced in national standards, while others are little known except to those who deal in them on a regular basis. Below are some basic definitions that I am frequently asked about. I hope this helps! Day … Read more
