There are a number of potential solutions to the classic EMC problem of providing immunity from mains borne interference, especially in the form of surges, sags, brownouts, lightning strikes and noise ...

While troubleshooting the power supply of a 1970s Centurion system, [Usagi Electrics] came across a fascinating feature of these units: the ferroresonant, or constant voltage transformer (CVT). The ...

Capacitor Voltage Transformers (CVTs) are central to modern power systems, where they not only scale high transmission voltages into measurable signals but also ensure the precision needed for ...

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 ...

Maxwell Technologies, Inc.'s new Electronic Voltage Transformer (EVT) is for smart grid applications that range from 110 kV to 550 kV. The EVT is the latest addition to Maxwell's CONDIS® family of ...
