Why should the DEIS care about the Smart Grid?

The Smart Grid is many different things to many different people, and the value proposition for the dielectrics and electrical insulation community is very different to that perceived by other groups, such as network control engineers or protection specialists. At first glance, Dielectrics and Electrical Insulation may seem rather distant from the Smart Grid; in reality, the Smart Grid could offer a wealth of information about the performance of dielectrics out “in the wild”. If the dielectrics community is able to utilise this information to its full potential, the grid as a whole stands to benefit.

Insulation Testing of Turbo Generators

Turbo Generators are designed for operation over a long period of time. High quality stator winding insulation is an important factor to achieve the expected reliability and forced outage rates. This course will provide basic description of stator insulation components and systems. It will include an overview of technical principles, applications and testing requirements outlined in IEEE 56, IEEE Guide for Insulation Maintenance of Electric Machines, along with some points from IEEE 4, 43, 95, and 286.
