#Real-life Transformer: Robotic bug springs to life The latest advancement in robotics may not look like much just a few small batteries attached to a flat sheet of paper
This real-world Transformer developed by computer and electrical engineers at the Massachusetts institute of technology (MIT) and Harvard university, could change the field of robotics.
See video of the real-life transformer in action Origami robots The new robots were inspired in part by origami, the Japanese art of paper folding.
which uses an electromagnetic field to transfer energy between two coils is used in transformers and wireless toothbrushes.
This effort will improve outage detection, transformer load management, and allow for smart and remote metering,
TRANSFORMER DRONES? The research team envisions a broad range of applications for their technology. For example, an unpiloted air vehicle might change shape from one designed for a cruise mission to one designed for a dive.
before paying for new wires, poles and transformers upgrades. It would also put existing DERS in front of utility contracts and procurements for distributed energy,
In either case, it much cheaper than a transformer upgrade. In other words, Hanley said, e think we can run a business off of that.
Its simplified control system uses power converters to allow connection of a variety of power sources to a small, high-frequency transformer.
#More efficient transformer materials Almost every electronic device contains a transformer. An important material used in their construction is electrical steel.
Transformers convert the standard voltage from the wall outlet into the lower voltages required by electronic devices.
Similar but more powerful transformers are used in electricity substations to convert the high voltages of the transmission grid into the standard AC power supply delivered to households.
All transformers have the same basic structure: a pair of iron cores around which wires of different lengths are wrapped.
These are the transformer coils one of which generates an oscillating magnetic field while the other converts this magnetic field into a voltage.
However unlike transformer steel these materials do not have oriented a grain structure and therefore possess different magnetic properties.

climb walls and even transform into a TANK Researchers have unveiled the nearest thing yet to a real-life transformer-a human sized robot that can walk,
Others, like pole-top transformers, may be right next to power lines, but can effectively use that electricity to run digital devices,
The sensors could also be useful along high voltage lines or in transformer substations. Electric fields
#Preventing transformer explosions Transformer failures have cost human lives when things have gone seriously wrong says Hkon Nordhagen a materials specialist at SINTEF in Trondheim Norway the largest independent research organisation in Scandinavia.
Large oil filled transformers are found in all power and switching stations as well as in many large buildings.
Today transformers are installed in stiff steel tanks. The risk of explosions can be reduced if the industry changes to soft housings that absorb energy in the same way as modern car bodies he says.
The idea of using automotive industry technology in transformer housings has led to a pilot project in which SINTEF's materials and electricity experts are collaborating.
All large transformers use oil for insulation and cooling as this greatly reduces energy losses and improves reliability compared to dry type transformers.
The increasing focus on energy efficiency actions might also enforce a substitution of many smaller dry isolated transformers with oil filled transformers.
Statistics suggest that internal failure will occur on average in about 15 of Norway's 3000 transformers every year.
The arc which occurs in such situations makes the oil evaporate and form combustible gasses.
and extremely rapid pressure build up in the transformer tank. If the tank ruptures combustible gases will leak out.
and any combustible materials in the vicinity of the transformer can catch fire. The fire may also be fed with oil from the tank.
#Transformers are equipped with relay protection that disconnect them from the grid within a few power cycles
#Additionally transformer tanks are reinforced by means of welded steel beams in order to make them withstand pressure rises
On one hand the transformer tanks are able to withstand more pressure than they could have done without the reinforcement on the other the extra stiffness means that they cannot expand
Our idea is to design transformer tanks in such a way that they expand when their internal pressure increases without risking that major rises in tension
If such an expansion is allowed there will be more time available for the transformer to be disconnected from the grid before rupture occurs.
The aim of the recently launched transformer safety pilot project is to pave the way for a large-scale competence-building main project.
With better knowledge and new mathematical models we will be able to observe the relationships between the physics of electric arcs the transformer tank and the electrical protection system.
