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 ...

Average current-mode control (CMC) requires that the total waveform of the current be reconstructed for the control loop. This article presents the steps required to select the transformer and how to ...

“While most current transformers may look the same on the outside, it’s what’s inside that counts,” according to Meramec Instrument Transformer Co. April 29, 2016 “While most current transformers may ...

EPCOS has developed two series of current-sense transformers that are particularly suitable for compact dc-dc converters because of their SMT design EPCOS has developed two series of current-sense ...

Current transformer (CT) saturation presents a critical challenge in the realm of power system protection and automation. Under fault conditions, the magnetic core of a CT may become saturated, ...

The units feature an intuitive orange three-position (Operating, Shorting and Measuring) disconnect lever. Engaging the lever fully automatically short-circuits the transformer when using the required ...

Transformers have been the backbone of power grids for over a century, but today’s demands for renewable energy, electric vehicles, and smarter grids are exposing their limits. Enter solid-state ...

Whenever a power or distribution transformer is isolated from the power system, it is probable that residual magnetism remains in the core due to the phase shift. However, residual magnetism also ...
