What is the difference between PA ground and PE ground?
Thread Content
Is there any difference between PA grounding and PE grounding? When connecting instrument cabinets today, the grounding effects in the two cases were completely different. Could some expert give me some advice?
PE ground refers to protective ground; I’ve never heard of the term PA ground – it’s confusing.
Common grounding symbols: PE, PGND, FG – protective ground or chassis； BGND or DC-RETURN – DC – 48V(+24V) power supply (battery) return path ； GND – Ground ； DGND – Digital ground ； AGND – Analog ground ； LGND – Lightning protection ground
PA might not be the right place. . . .
Learned the common grounding symbols: PE, PGND, FG – protective ground or chassis； BGND or DC-RETURN – DC – 48V(+24V) power supply (battery) return path ； GND – Ground ； DGND – Digital ground ； AGND – Analog ground ； LGND – lightning protection ground; I really don’t understand PA. I hope experts can explain it
I also want to know; looking forward to an expert’s explanation
Could it be the intrinsically safe instrument grounding busbar? ?
Haven’t heard of PA, let’s learn it!*
PE for protective grounding, PA for equipotential grounding
The people upstairs are really great; I’ve also heard of PA for the first time
Everyone, is there any detailed information on various grounding methods? Could you please provide some materials? Thank you!
