It’s important to always test ground fault protection systems during commissioning to avoid nuisance trips.
There are only three levers available to reduce an arc flash event’s potential injury to electrical workers: energy, time, and distance.
Identify and correct issues in systems without modern substation controls and communications systems.
Performing arc-flash studies for low-voltage power distribution equipment can present challenges that require engineering judgement and proper documentation.
SF6 gas is used to quench the arc that is created when a breaker interrupts a fault in high- and extra-high voltage equipment. Maintenance is key to keeping SF6 equipment operating safely.
Avoid normalizing bad habits to improve safety and reliability in your electrical substation.
Keeping up with standards and regular testing, maintenance, and field service help mitigate arc flash risks.
Understand how the changes to IEEE 1584 impact incident energy and arc flash boundary calculations to know if your arc flash study is still valid.
