Floating Power stations
Power generation and marine technology are successfully integrated in floating power plants. Floating, barge mounted power plants are constructed cost effectively and rapidly in well controlled industrial settings. They can easily be relocated and are therefore an ideal solution for power production on an interim basis as they can be connected to the grid to alleviate local power shortages where and when needed. Floating power plants can also provide a rapid answer to increased power demand in advance of coming land based power plants. Advantages of a floating power plant is that it Provides fast supply of electricity to areas with limited infrastructure. It is a mobile asset, possible to relocate or trade. It does not require a large site and is independent of soil quality.
Low smoke cables
A low smoke cable has a LSZH sheath. LSZH stands for Low Smoke Zero Halogen and refers to the compound making up the sheath of a cable. In the event of a fire, this type of sheath will emit very low levels of smoke, and non-toxic levels of poisonous halogen gases (typically under 0.5% HCl emission).After the King’s Cross fire in London in 1987 it became mandatory to use this type of sheathing on all London Underground cables since the majority of fatalaties occurred through gas and smoke inhalation rather than directly from the fire itself. This type of sheathing is mainly recommended for use in highly populated enclosed public areas.Other equivalent terms for this type of sheathing are LSHF (Low Smoke Halogen Free), LS0H (Low Smoke Zero Halogen), 0HLS (Zero Halogen Low Smoke).
Written-Pole Technology allows the magnetic pole pattern on the magnet layer to be changed to a desired pattern while the machine is rotating and therefore breaks the relationship between rotor speed and output frequency. Written-Pole motor employs one of three modes of operation based on the rotational speed of the machine namely start mode, written pole mode & run mode. Written Pole motors use similar construction techniques found in conventional motors. A continuous layer of ferrite magnets on the surface of the rotor, along with a high-density exciter winding contained within the stator winding. The basic platform consists of conventional steel shaft inserted into a lamination stack containing a high resistance rotor cage.
Maglev Train is a system of transportation that uses magnetic levitation to suspend, guide and propel vehicles from magnets rather than using mechanical methods, such as wheels, axles and bearings. Download Full Seminar

Electrical Engineers role in Aerospace Industry can also be mentioned in your presentation slides.
Fire Retardant Tapes
Fire Retardant tapes function as a fire barrier to meet more demanding fire propagation and fire survival requirements. These tapes are based on a finely woven glass substrate, which has intrinsic fire retardant properties, and the surface coating also gives weave stability. All of these tapes are free from halogens and sulphur.The high tensile strengths give the additional benefit of excellent binding properties. There is a semi-conducting version available to complement the rest of the insulative range. It act as a barrier between the flame and the combustible core/insulation within the cable. Retains the integrity of the cable during and after exposure to fire. Extends the fire-survival time of the cable and its functions.
Solid Oxide Fuel Cell
A solid oxide fuel cell (SOFC) is an electrochemical conversion device that produces electricity directly from oxidizing a fuel. Fuel cells are characterized by their electrolyte material; the SOFC has a solid oxide or ceramic, electrolyte. Advantages of this class of fuel cells include high efficiency, long-term stability, fuel flexibility, low emissions, and relatively low cost. The largest disadvantage is the high operating temperature which results in longer start-up times and mechanical and chemical compatibility issues.
Infrared thermography is equipment or method, which detects infrared energy emitted from object, converts it to temperature, and displays image of temperature distribution. To be accurate, the equipment and the method should be called differently, the equipment to be called as infrared thermograph and the method to be called as infrared thermography. Recently, however, more and more public literatures show tendency not to pay attention to such appellative. We call our equipment as infrared thermography considering such generalization of the terminology.Characteristics of Infrared Thermography equipments are :It captures as a temperature distribution on a surface,and it can display as a visible information,Temperature can be measured from a distance without contacting an object,Temperature can be measured in real time.
Wireless power transmission (Download pdf )
The concept of transmitting power without using wires i.e., transmitting power as microwaves from one place to another is in order to reduce the transmission and distribution losses. This concept is known as Microwave Power transmission (MPT).Wireless Power Transmission system would completely eliminates the existing high-tension power transmission line cables, towers sub stations between the generating station and consumers and facilitates the interconnection of electrical generation plants on a
global scale. It has more freedom of choice of both receiver and transmitters. The Capital Cost for practical implementation of WPT seems to be very high and the other disadvantage of the concept is interference of microwave with present communication systems. Common beliefs fear the effect of microwave radiation. But the studies in this domain repeatedly proves that the microwave radiation level would be never higher than the dose received while opening the microwave oven door, meaning it is slightly higher Download pdf now

Non Conventional Energy Sources
SCADA (supervisory control and data acquisition) generally refers to industrial control systems (ICS): computer systems that monitor and control industrial processes including those of manufacturing, production, power generation, fabrication, and refining, and may run in continuous, batch, repetitive, or discrete modes.Infrastructure processes may be public or private, and include water treatment and distribution, wastewater collection and treatment, oil and gas pipelines, electrical power transmission and distribution, wind farms, civil defense siren systems, and large communication systems.Facility processes occur both in public facilities and private ones, including buildings, airports, ships, and space stations. They monitor and control HVAC, access, and energy consumption.
PPTC Devices for Protection of Battery Packs
PPTC circuit protection devices are made from a conductive polymer blend of specially formulated plastics and conductive particles. At normal temperature, the conductive particles form low-resistance chains in the polymer.However, if the temperature rises above the device's switching temperature, the crystallites in the polymer melt and become amorphous. The increase in volume during melting of the crystalline phase causes separation of the conductive particles and results in a non-linear increase in the resistance of the device. The heating can take place due to an increase in ambient or cell temperature, or it can be generated by resistive heating as in the case of an overcurrent condition. It can also be a combination of the two as in the case of a faulty charge.
The Piezoelectric effect in piezoceramics converts electrical field to mechanical strain. Under special electrical excitation drive and ceramic geometry of Nanomotion motors, longitudinal extension and transverse bending oscillation modes are excited at close frequency proximity. The simultaneous excitation of the longitudinal extension mode and the transverse bending mode creates a small elliptical trajectory of the ceramic edge, thus achieving the dual mode standing wave motor patented by Nanomotion.By coupling the ceramic edge to a precision stage, a resultant driving force is exerted on the stage, causing stage movement. The periodic nature of the driving force at frequencies much higher than the mechanical resonance of the stage allows continuous smooth motion for unlimited travel, while maintaining high resolution and positioning accuracy typical of piezoelectric devices. Travel can be linear or rotary, depending on the coupling mechanism.
DDR refers to Direct Drive Rotary Motors.High-pole, permanently excited hollow shaft synchronous motors. They are directly coupled with the load via the hollow shaft and enable high-precision, smooth operation, maintenance-free, extremely stiff drive solutions with very good dynamic features.
