When size offers no protection from danger
Danger in the natural world is not always large or obvious. Some of the smallest creatures on Earth possess toxins, diseases, or behaviors that can cause serious harm to humans. Encounters are often ...
Abstract: This paper discusses the factors to consider for sizing current transformers (CTs) for line protection applications. We first cover CT basics, with emphasis on errors and ac and dc ...
