Inadequate shielding and bad grounding are often blamed when measurements are inaccurate, especially in high-impedance applications. In fact, shielding and grounding problems are frequently ...

HISTORY: High Resistance Grounding is a means of limiting ground fault current in electrical systems. Unrestrained fault current can cause severe equipment damage, product destruction, and personnel ...

In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

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 ...

This application note presents the application and specification of signal transformers. It also describes the basics of wideband transformers and autotransformers, and its design equations. This ...

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 ...
