Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

I am trying to acquire more information on Electrical Substation Planning.

I would be grateful if any planer with an Electrical Engineering background can help with suggesting a WBS for designing and building an Air-Insulated-Substation.

I would presume that the first 2 levels would be as follows :

SS.1 Design Phase
SS.2 Procurement
SS.3 Civil Works for Substation Building
SS.4 Installation Works
SS.5 Testing & Commissioning

Electrical Engineering is not my specialty, and I was not assigned to create a schedule. I’m only trying to learn more about the subject.

Regards

Shahul,

Thank you very much, but im preparing only the construction part of the substation like Civil, MEP and Finishing work without the procurement activities. I’ll just want to know the more or less the duration for Civil, MEP and Finishing for a 6,000 m2 substation.

Thank You
Pacifico

Hi Pacifico

Check the long lead material procurement duration with your project team because in substation you will find many equipment on approval of submittal they will undergo factory acceptance test which consumes some duration in some case it is critical

Dear Pacifico,

It depends on the location and the environmental factors. Say you need 3-6 months for procurement of equipment, and during that time you can get the Civil Structures up.

Say 9-12 months as as starter.

With kind regards,

Samer

Hi Hady,

Installation works in the substation can be broken into following;

1. Installation

1.1. MEP works inside substation
1.2. Installation of substation equipments (transformers, MDSs etc)
1.3.Power Cable Installation
1.4.Bus duct installation
1.5.Control Cables installation
1.6.Cable terminations.

2. Testing activities

2.1.Transformers and Panels dry check
2.2.Cable testing
2.3.Transformers and Panels testing (protection tests)
2.4.System sequence tests
2.5.Cable HIPOT tests
2.6.Authority Inspection and witness tests
2.7.Final commissioning and Power On

Hope this will help

Hi Adi

Just make sure that you can get the kit into the building before you seal it up.

Best regards

The construction of a concrete substation is like any other concrete building but you need lots of block-outs. If it is air-insulated, then you have air-conditioning system.
