Grounding and bonding portable generators and stages
... Systems. For example, under normal circumstances, when we run a 4/0 feeder cable system to a portable stage, the green grounding conductor needs to be at least #2 wire. Typically, we use the same size grounding conductor as the phase conductors for simplicity. The reason it can be sized smaller than ...

Computational Intelligence, Condition Monitoring and Optimization in Mechanical System- A Review
... At first the factors that influence failure mode detection are identified. Then a model is suggested based on a fuzzy inference system. The detection rate is modified and relay performance is calculated using the Bayes theory. The model validation is reviewed from two points of views. Finally, an il ...

10 kW Contactless Power Transfer System for Rapid Charger of
... In a contactless power transfer system with a series resonant capacitor, the primary terminal voltage increases with increasing power. This overvoltage may lead to the problem of breakdown voltage of capacitor and the breakdown of winding insulation. To prevent such an overvoltage occurring, it is s ...

AN4704, 3-phase Sensorless BLDC Motor Control Kit with the S12
... The exact position of the rotor can be sensed by measuring the BEMF voltage induced by the rotating permanent magnet in the unpowered phase. In Figure 5, the green windows mark the time periods in which the respective phase is unpowered. The voltage measured in this time window is the BEMF voltage. ...
