IEC 61000-5-2
يجب عدم تنفيذ شبكة أرضي منفصله للتيار الخفيف ولا شبكه منفصله للحمايه من الصواعق ، وتبقي هي شبكه واحده فقط

IEC
لما بيكشف عن مشكله بيقول حلها . . في نفس ال IEC الصفحه اللى بعدها علطول أعطي لنا Recommended configuration للشبكات الثلاثه مع بعض .. وهنلاقي انهم عباره عن شبكة أرضي واحده فقط .. و ده ظاهر في الصور المرفقة

Form of separation

What is The form
IEC 61439 'Low-voltage switchgear and control gear assemblies', specifies standard arrangements of switchboard (call forms of internal separation).
Types of form
The are labelled as Form 1, Form 2, Form 3 and Form 4. Forms 2, 3 and 4 are further broken down into Form 2a, 2b, 3a, 3b, 4a and 4b.
Each Form relates to the internal separation of the busbars, functional units and terminals, each being defined as:
1️⃣Busbar - low impedance conductor to which several electric circuits can be connected
o Main busbar - busbar to which one or more distribution busbar, incoming unit or outgoing unit can be connected
o Distribution busbar - busbar in one section which is connected to the main busbar from which incoming or outgoing units can be connected
2️⃣Functional Unit - part of the assembly comprising the electrical and mechanical elements that contribute to the fulfilment of the same function
o Incoming unit - functional unit which feeds energy into the assembly
o Outgoing unit - functional unit supplying energy to the outgoing circuits
3️⃣Terminals - part of the assembly which provide for connection of incoming and outgoing cable and busbar

MEP BIM Services
The term MEP stands for Mechanical, Electrical, Plumbing and Piping services. Our MEP BIM services include different sets of work that plays a vital role in the success of the construction project. We and our team are expertise for 3D model creation, Clash Coordination, Preparation of the set of construction documents, review of construction documents, and other important BIM services.

We at Silicon Info ensure that our BIM services are followed and compliant to all necessary construction standards and BIM codes that are applicable across different locations and countries. Our BIM engineers are well-versatile and expert enough in handling Architectural and Structural design during the entire process of MEP BIM modeling and Co-ordination process.
