طراحی سیستم ارت و زمین مراکز داده
همانطور که در مراکز داده و امکانات مرتبط درستی طراحی و در نظر گرفتن ملاحظات ضروری است ،سیستم ارت مرکز داده هم بسیار مهم است که به نصب و تعمیر و نگهداری سیستم های متصل شده به ارت مرتبط می شود.هزینه های نگهداری مرکز داده و هزینه های خرابی تجهیزات خسارت سنگینی را ایجاد می کند.این سند مبانی پایه سیستم های قدرت، تعاریف و الزامات اساسی را ارائه می دهد.
این مقاله بررسی ناهنجاریهای نصب و راه اندازی مشترک و مسائل مربوط به ساخت و ساز را ارائه می دهد و فهرستی از آنها را ارائه می کند.
انواع سیستم های منبع تغذیه وابسته به زیرساخت توزیع شبکه برق منطقه است. برای تجاری وسیستم های صنعتی، انواع منابع قدرت به طور کلی به چهار دسته گسترده تقسیم می شوند .
در داخل سند به تفصیل مباحث فوق بیان شده است.
طراحی کننده سیستم ارت مرکز داده می بایست برای حفاطت مرکز داده با چالش ها و مشکلات موجود در این صنعت آشنا باشد و در انطباق با حفاظت الکترومغناطیسی مراکز داده حتما ملاحظات سفارش شده را در نظر بگیریم.

In order for data centers and related facilities to properly operate as designed and intended, it is extremely
important that care be given to the effective installation and maintenance of bonding and grounding systems.
This paper presents the fundamentals of power system grounding, fundamental definitions and requirements
of the National Electrical Code® (NEC®) with respect to grounding, the need for low voltage ground fault
protection and how it is implemented, and special grounding requirements imposed by the data center
operating environment. This paper also provides a summary of the applicable NEC articles, a review of
clauses from specific IEEE® Standards, and listing of other references related to bonding and grounding in
data center facilities. This paper also outlines and explains the principal purposes for an effectively bonded
and grounded system. Also addressed are the requirement of four-wire systems versus three-wire systems,
arrangements that require the installation of modified differential ground fault (MDGF) protection system, and
the effects of system grounding upon surge protection and power quality.
This paper reviews common installation inadequacies and construction issues, and will provide a list of
common conditions that cause bonding and grounding systems within data center facilities to become
inadequate or deteriorated over time. Testing and maintenance requirements of grounding systems are also discussed
