An AC resonant test system is designed to generate high alternating voltage by forming a resonant circuit between the reactor and the test object. By operating at or near resonance, the system can ...

Overvoltage protection of AC power lines is a common practice, which encompasses a variety of protection circuit solutions. Most designs are cost-driven and tend to use only the bare minimum of ...

When choosing a switch to use in an electrical design project, there is a perception that it is possible to use any switch, provided its current rating is greater than the maximum load in the circuit.

Several different technologies and designs are available among solid-state switches today. The major families are the standard Triacs (triode for alternating current), the snubberless Triacs, and the ...

The National Electrical Manufacturers Association (NEMA) has published SG 4-2009 Alternating Current High-Voltage Circuit Breakers. The standard, which NEMA published under license from IEEE, was ...

Munich – Schaltbau has introduced a special innovation for AC-driven electric locomotives and multiple units: an AC vacuum circuit breaker that can almost do without any secondary supply energy for ...
