Induction motors are widely used worldwide for domestic and industrial applications. Fault detection classification techniques based on signal analysis have increased in popularity due to the growing use of induction new technologies such as electric vehicles, automatic control, maintenance systems, inclusion renewable energy sources electrical among others. Hence, monitoring, fault detection, ...

Operation of traditional fieldmeters typically relies on mechanically actuated capacitance for DC fields measurement. This paper provides theoretical background for operation of an electric field sensor with a solid state variable capacitor. Design is supported by circuit and FEA models, illustrating the operation. Theoretical work is verified against results of sensor’s tests performed in DC, ...

We show that a simple (few-element) arrangement for wavelength-multiplexed digital holography allows the measurement of the electric field E x ,y , t of a femtosecond laser pulse on a single shot. A slightly rotated twodimensional diffractive optical element and a variable-wavelength filter together generate multiple spectrally resolved digital holograms that are simultaneously captured in a si...

Flash sintering is one of the newest techniques for sintering ceramics to near full density. It occurs in an appropriate combination of temperature and electric field. Temperature measurement is one of the most serious challenges in this process. In the present study, we tried to model a flash sintering process of 8YSZ and 3YSZ with finite element method to make an assessment for temperature di...

The proliferation of non-linear and time-variant loads is causing a number of disturbances on the electric network, from a more and more significant distortion of both currents and voltages, to transient disturbances on the supply voltage. In this respect the electric network behaves as an "healthy carrier" of disturbances, so that a disturbance generated by one customer can be distributed to o...
