A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...

The primary function of a current transformer (CT) is to provide accurate current information to protective relays. But when a CT saturates and can no longer perform this function, the lack of ...

Omicron has introduced a way to test current transformers at all lifecycle stages by using a testing method called "the modeling concept". The "traditional" way of testing a current transformer is to ...

Common methods used to measure current. A new approach to current sensing: GaNSense technology. For any electrical control system, input signals of both voltage and current are critical for the system ...

This article is based on the 1999 National Electrical Code (NEC). Installing transformers in accordance with the NEC is critical to ensuring a safe electrical installation as well as a reliable power ...

After a national arc-flash hazard analysis project was performed at eight recently constructed parts distribution warehouse sites for a Global 100 company as part of an OSHA Voluntary Protection ...

Electric current is electric charge in motion. It can take the form of a sudden discharge of static electricity, such as a lightning bolt or a spark between your finger and a ground light switch plate ...
