Advance Electrical Design & Engineering Institute


Advance Electrical Design & Engineering Institute ESD Training Covers Practical design of the electrical supply and the specification of the equipment needed in modern Generation , Transmission ,Distribution , oil, gas and petrochemical plants. Also part of protection, utilisation and safety hazards and reliability requirements.

During The Training Programs Detailed worked examples are also given to demonstrate the subject with practical parameters and data.








Advance Electrical Design & Engineering Institute Electric power transmission is the bulk transfer of electrical energy, a process in the delivery of electricity to consumers. A power transmission network typically connects power plants to multiple substations near a populated area. The wiring from substations to customers is referred to as electricity distribution, following the historic business model separating the wholesale electricity transmission business from distributors who deliver the electricity to the homes.


Advance Electrical Design & Engineering Institute •Provide an alternative path for the fault current to flow so that it will not endanger the user

•Ensure that all exposed conductive parts do not reach a dangerous potential •Maintain the voltage at any part of an electrical system at a known value so as to prevent over current or excessive voltage on the appliances or equipment.

•Transmission •Substations & Power Generations •Telecommunication •Transformer Neutral Earthing •Lightning Arrestor Earthing •Equipment Body Earthing •Water Treatment Plants •Heavy Industries •College, Hospitals, Banks •Residential Building


Advance Electrical Design & Engineering Institute Lighting is primarily provided for people, not for the buildings or roadways or objects illuminated. Peoples’ needs should determine what kind of lighting is provided.

Power systems analysis software allows users to simulate electrical power system

networks quickly and easily to judge their correct, safe and timely operation

Single -line diagram, Short Circuit Analysis Ampacity, Load flow Analysis ,Cable Sizing, and Transmission Line Constants, provide integrated as well as stand-alone capabilities

to design, analyze, and size equipment.


Thousands of companies, electric utilities, and government agencies worldwide rely on power system for the design, analysis, maintenance, and operation of their most critical

electrical power systems.

Advance Electrical Design & Engineering Institute Potential of solar energy What is Photovoltaic (PV)? Photovoltaic means turning daylight directly into dc electricity Done by photovoltaic cells (PV cells), assembled into PV modules  There are no moving parts

 There is no 'fuel', apart from daylight  The modules need no maintenance  In principle, almost indefinite lifetime

Central power plant Offices PV power plant

PV works with both direct sunlight and indirect daylight (more light = more power)
