The Course enables the entry level and working engineers to understand the basics, different systems used in Electrical for Domestic and commercial purposes.

To achieve the optimal design, one should needs good analytical skills and up-to-date technical knowledge of various system designs. This training is useful to design Electrical Building Services. This training is an opportunity to apply the academics and develop an understanding of how to develop solution-driven concepts and translate them into a complete set of plans and prototypes.

Electrical Required in Commercial Buildings, Airports, Shopping malls, Petrochemical complex, refineries, pharmaceutical industry, Aerospace industry, Hospitals etc..,

Electrical designing is a branch of electrical engineering which enables Electrical engineer to size electrical equipment’s used in building services. Electrical design involve, estimation of load, sizing, planning and testing wrt Codes and make schematic drawings.

We will work on lighting equipment, power systems, power distribution, fire and life safety systems

To get power we require Distribution transformer, switchgear for protection, cable for transmission of power and measuring instruments for measuring variable quantities like current, voltage, fault current etc.

Can we live without Electricity? The answer is the future of this Course.
