We are a New York City Agency and have been using electrical standards for many years which requires PC's and associated equipment such as scanners , printers etc to be provided isolated ground and each individual circuit carry a separate neutral.All such equipment is wired to dedicated computer panels and convenience receptacles are wired to separate panels without isolated ground.
Currently what I hear and read from experts is that this method of providing isolated ground is old and not required any more. One of the reason given is the cost, and the modern computers are more resilient to distortions and transients due to non-linear loads in the system . Besides other means are available to provide clean power, one using surge suppresors and the other by K rated transformers etc.
Before we review the agency's standards for updates I would like to know your opinion and experience in general on this isolated grounding issue. Thanks.
