Ground Fault Protection
Ground Fault Protection is a safety system that helps prevent electrical accidents and fires in buildings and industrial settings. Think of it like a very fast safety switch that turns off power when it detects dangerous electrical problems. It's similar to the common GFCI outlets in home bathrooms, but on a larger, industrial scale. Electrical engineers and technicians work with these systems to keep people safe and comply with electrical safety codes. When reviewing resumes, you might see it referred to as GFP, Ground Fault Protection Relay, or Ground Fault Circuit Protection.
