Conceptual survey of generators and power electronics
... three phase AC-grid. Many different concepts have been developed and tested since. Activities in this field were encouraged by the oil crisis in 1973. Twenty years ago the concept of the Riisager wind turbine (22 kW) initiated a new area. The concept was similar to the innovative Gedser wind turbine ...

An Introduction to SAFETY ANALYZER
... • In the event of a fault that would otherwise cause an exposed conductive part to become live, the supplementary protection (i.e. the protective earth) comes into effect. A large fault current flows from the mains part to earth via the protective earth conductor, which causes a protective device (u ...

step-up transformer
... Two Types of Transformer A step-up transformer increases the voltage there are more turns on the secondary than on the primary. A step-down transformer decreases the voltage - there are fewer turns on the secondary than on the primary. To step up the voltage by a factor of 10, there must be 10 time ...

... Brushless DC (BLDC) motor is a permanent-magnet synchronous machine with a sixtransistor inverter whose on/off switching is determined by the motor’s rotor position. It has neither brush nor commutator. With no possible brush/commutation failure, its torque-speed characteristic is similar to that of ...
