Electrical System In A Building

The electrical system in a building is one of the indispensable systems to ensure the smooth and safe operation of the building.

Role of the electrical system in a building

The electrical system is considered the most crucial part of the entire building. It is the primary source of energy to ensure the lighting needs, the smooth operation of the electrical system, such as elevator systems & heating, ventilation, and air conditioning systems, fire protection systems, communication systems such as telephones, internet, lighting systems, and electricity for the building.

The general structure of the electrical system in a building

A professional consulting unit in operation and management buildings must understand clearly the structure of building electrical systems to bring the most prompt and effective solution for electrical problems. The general structure of an electrical system in a building includes

• Extra low voltage system: LAN and Internet, Telephone, CCTV, IPTV, Public Audio
• Extra high voltage system: Lighting system, emergency lighting, lightning protection system, grounding system…

How to read electrical diagrams?

Electrical system diagrams are not easy to read, it is necessary to have knowledge of electrical circuit symbols, amplifier circuits, etc. Besides, the building management board should follow these additional methods to reading the electrical system diagrams:

• Learn how to use and the role of devices in electrical circuits through the information on their parts.
• Consult the parameters of electrical devices, calculate the true values ​​of voltages and resistances and find out the relationship between them.
• Components must be installed in the correct electrodes (anode and cathode) and a fixed direction. Alternatively, you can look at the long metal pins to see the polarity of these components.
• Determine how each electrical circuit works and functions based on the electrical diagram in the building.

Reading instructions for a building's electrical system 

The operation of the electrical system in a building 

The building management board also needs to design a reasonable and efficient electrical system operation process. The operation of the electrical system is as follows:

Step 1: Check and monitor the electrical system

Observe the electrical system diagram to determine the quantity and location of equipment. Then, proceed to turn on the CB to be able to supply power to the system. Finally, check devices such as indicator lights, voltage indicators, power supplies, etc.

Step 2: Power on

When the electrical system is ready, you can power the electrical system and equipment to ensure efficient operation.

Step 3: Check the electrical system status 

To ensure efficient system operation, management should regularly check equipment based on electric meters. In addition, pay attention to electric parameters to review and maintain errors promptly.

Step 4: Shutdown

Shut down and then check all technical errors in the equipment.

Step 5: Repair and periodic maintenance system

The system needs maintenance and repair after a long time of use. Therefore, it is necessary to review and evaluate the status of the electrical system when taking periodic technical maintenance of the building. Takers must come up with an appropriate maintenance plan to ensure the system operates more safely.

Aiming to bring the best quality service to customers, Taisei VN provides management & operation services and cooperates with other reputable units in building electrical maintenance. Taisei VN will invite specialized units for each system to evaluate and offer the most suitable solutions for essential consultation and intervention. We will strictly supervise the process to guarantee your facilities.
