Connect Isolated Ground To Earth Physics Forums Participants express differing opinions on whether to connect the isolated ground to the chassis and earth. some advocate for connection to reduce noise, while others caution against potential issues like ground loops, indicating that the discussion remains unresolved. All grounds are connected through their separate grounding connections (field and control system). instrument systems use a common ground point but in the field are isolated from local grounding to avoid ground loop currents.
Trying To Better Understand The Physics Of Electrical Earth Ground After a number of attempts to solve the problem, i finally found something that worked: if i used a jumper to hook the ground of the programmer to earth ground from the mains, and it alleviated the problem. When implementing an isolated rs 485 system, two isolated power supplies can be used to eliminate the ground loop by having the isolated ground connected to the remote ground connection and the non isolated ground connected to earth. One participant questions the safety of attaching dc ground to the chassis, which is also connected to ac earth, and whether this compromises isolation provided by ac dc supplies. Participants express a range of views on the necessity and implications of grounding versus floating power supplies, with no clear consensus reached. some advocate for grounding based on safety and regulatory compliance, while others highlight the potential benefits of isolation in certain designs.

I'm wondering whether to isolate the control box back plate from ground (pe) and fit an earth line choke (as part of a mains filter) between the back plate and the earth line input. The earth ground is used for safety and should not be used as the reference. earth ground and the probe grounds are separated by high resistance and would give an inaccurate measurement. It is best to connect the shielding to earth ground as it will present to lowest resistance path for unwanted energy (esd etc) from reaching any circuitry inside the enclosure and might damage it. In order to prevent ground loops an analog shielded cable shield is grounded at one end only and at only one ground point. does this mean that "each" single analog cable can have it's own single ground point?.
