electrical calculation of generator

The Electrical calculation of generator :

We have explained the components of the process for projects, starting from the ring main unit(RMU) up to the low voltage and load distribution board, So We will  complete the calculations of the electrical generator used in the projects, whether like hospitals, tourist villages, or others.

We will calculate emergency loads only, for example:

• lighting =25KVA
• lifts load = 500 kvA
• smoke exhaust fans = 60KVA
• pump load = 20KVA
• computer Loads = 30kVA
• operation room = 150KVA

We all know that loads are divided into static loads and dynamic loads :

• Static loads = computers +lighting
• Dynamics Loads = Lifts+ Smoke exhaust fans + pump loads +operation Rooms
• Rate of generator = 1*KVA for static + 2*KVA for dynamics
