With the SCT5564 ring-type current transformer, Beckhoff offers a universal current-sensitive measurement system for AC and DC differential currents in conformance with the EN/IEC 62020-1 standard.

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 ...

Current transformers can perform circuit control, measure current for power measurement and control, and perform roles for safety protection and current limiting. They can also cause circuit events to ...

It is important for machine design engineers to understand how transformers work so they can design machinery that operates optimally within the proper voltage ranges, as well as select the right ...

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 ...

This article is based on the 2014 Edition of the National Electrical Code (NEC). All you wanted to do was install a 30kVA, 120/208V transformer to supply receptacles in a new office structure on the ...
