How Transformers Work. Transformers are a type of neural

Recurrent Neural NetworksLong-Short Term MemoryAttentionConvolutional Neural NetworksTransformersSelf-AttentionRecurrent Neural Networks have loops in them, allowing information to persist. In the figure above, we see part of the neural network, A, processing some input x_t and outputs h_t. A loop allows information to be passed from one step to the next. The loops can be thought in a different way. A Recurrent Neural Network can be thought of as multiple copies of the same network, A, each network passing a message to a successor. Consider what happens if we unroll the loop: This chain-like nature shows that recurrent neural networks are clearly related to sequences and lists. In that way, if we want to translate some text, we can set each input as the word in that text. The Recurrent Neural Network passes the information of the previous words to the next network that can use and process that information. The following picture shows how usually a sequence to sequence model works using Recurrent Neural Networks. Each word is processed separately, and the resulting sentence is generated by pa...Get price

The IEEE transformer committee handles all matters related to the application, design, construction, testing, and operation of transformers, reactors, and other similar equipment. The IEEE Transformer Committee met in Dallas in 2007 to revise the existing guide for routine testing in the field, IEEE 62, Guide for Diagnostic Field Testing of Electric Power Apparatus - Oil Filled Power Transformers, Regulators, and Reactors (R2005). At the time, a vast number of old and new testing methodologies and practices were used in the field but not covered by the IEEE 62 standard. It was logical to create a new or revised guide under the C57 standard series. The C57 standards already contained other transformer-related guidelines administered and supervised by the IEEE Transformer Committee (Figure 1).

Power below the waves | TD World

The Deepwater FrontierWind InstallationsSubsea Distribution SystemThe exploitation of offshore oil in shallow waters is declining as these relatively local reserves diminish. Often, to maximize oil extraction, seawater or gas is pumped into the well to increase pressure and drive out the remaining fuel trapped beneath the seabed. Similar techniques are used in deepwater oil fields. As these are at much greater distances from the shore, they present additional challenges to the industry. Operations here require specialized knowledge and expertise, particularly when powering compressors, pumps and motors at depths of several kilometers, possibly 50 or 100 km away from the shore. Subsea technology makes oil and gas production possible at a depth of several kilometers and pressure-increasing compressors enable continued production in waning oil and gas fields. The performance levels required of deep-sea equipment are very high and reliability is decisive. Bringing low-loss power to remote offshore locations requires transmission at high voltage throug...Get price
