7. •Endpoint To Endpoint Long Haul Bulk Power
Transmission Without Intermediate Tap.
•Reducing Line Cost. Since HVDC Transmission Requires
Fewer Conductor.
•Increased Stability of Power System
•Reducing Losses(Corona loss, Skin effect)
•Lower Investment Cost because NO REACTIVE LOSS.
• Increasing the capacity of an existing power grid in
situations where additional wires are difficult or
expensive to install.
Why choose HVDC

8. WHAT IS SMART MATERIALS
SMART MATERIALS
 Smart material are those materials that posses
the ability to change their physical properties in a
specific manner in response to specific stimulus
input.
Stimuli could be pressure, temperature, electric &
magnetic field, chemicals, nuclear radiation etc.
The associated changeable physical property could
be shape, stiffness, viscosity, damping etc.

9. PROPERTIES OF SMART
MATERIALS
• Sensing materials and devices
• Actuation materials and devices
• Control devices and techniques
• Self-detection, self-diagnostic
• Self-corrective, self-controlled, self-healing
• Shock-absorbers, damage arrest

10. TYPE & EXAMPLE OF
SMART .
MATERIAL
 Piezo-electric polymer and ceramic(silk, DNA, ZnO
etc)
 Electro-rheological(ER) fluid(mixing cornflour in a
light vegetable oil or (better) silicone oil etc.)
 Magneto-strictive materials(cobalt ,terfenol D etc)
 Shape memory alloy (SMAs) (copper-aluminium-nickel
& nickel-titanium (NiTi) alloy etc)
 Fiber optics.

11. PICTURES OF SMART MATERIALS
Nitinol alloy Piezoelectric film, PVDF
Terfenol Material Piezoceramic, PZT

12. High energy density.
Excellent bandwidth.
Smart materials have better durability and reliability.
Smart materials reduces the production cost.
Smart materials reduces the weight of component
used in the mechanical & electrical industries.
Smart materials are gives excellent results in
Electrical Technology & Communication Technology.
Smart materials get smarter with ability to better
control of shape & size.
ADVANTAGES OF SMART
MATERIALS

13. LIMITATIONS OF SMART
MATERIALS
 Smart materials are very expensive.
 They are not easily available in market.
 They are very sensible so they need proper care while
storage it.
 Smart materials needs proper skill to recognize it
among other materials.

14. Conclusion
 Today, the most promising technologies for lifetime
efficiency and improved reliability include the use of
smart materials and structures. Understanding and
controlling the composition and microstructure of any
new materials are the ultimate objectives of research
in this field, and is crucial to the production of good
smart materials.
 New and advanced materials will definitively enhance
our quality of our life.
