A few years ago, the term “arc flash” crept into our electrical technical vocabulary. Since that time, performing arc flash calculations remains a challenge for many of us. Calculating incident energy ...

ABB demonstrated its new Arc Fault Circuit Protection solution at the Solar Power International conference and exhibition last week, in conjunction with Shoals Technologies. This solution uses new and ...

Differential protection is best understood as a fault control philosophy rather than a component category. The relay itself is secondary to the scheme it enforces. Once a zone is defined, the system ...

Power systems today operate in an environment where reliability and safety must be maintained despite rising loads, expanding interconnections, and increasing dependence on distributed energy ...

When the voltage at an input of a switch, multiplexer, or signal-line circuit protector exceeds the voltage that powers those devices, you define the excessive input voltage as a fault. This ...

Fault tolerant design focuses on keeping the system running or safe in spite of failures usually through the use of independent and redundant resources in the system. Implementing redundant resources ...

Most switching power-supply controllers provide non-latching fault protection. Satisfying a requirement for a latchoff response to a fault often requires the addition of excessive and redundant ...
