The data set contains electrical and mechanical signals from experiments on three-phase induction motors. The experimental tests were carried out for different mechanical loads on the induction motor axis and different severities of broken bar defects in the motor rotor, including data regarding the rotor without defects. Ten repetitions were performed for each experimental condition.

Instructions: 

Experimental Setup:

The experimental workbench consists of a three-phase induction motor coupled with a direct-current machine, which works as a generator simulating the load torque, connected by a shaft containing a rotary torque wrench.

- Induction motor: 1hp, 220V/380V, 3.02A/1.75A, 4 poles, 60 Hz, with a nominal torque of 4.1 Nm and a rated speed of 1715 rpm. The rotor is of the squirrel cage type composed of 34 bars.

- Load torque: is adjusted by varying the field winding voltage of direct current generator. A single-phase voltage variator with a filtered full-bridge rectifier is used for the purpose. An induction motor was tested under 12.5, 25, 37.5, 50, 62.5, 75, 87.5 and 100% of full load.

- Broken rotor bar: to simulate the failure on the three-phase induction motor's rotor, it was necessary to drill the rotor. The rupture rotor bars are generally adjacent to the first rotor bar, 4 rotors have been tested, the first with a break bar, the second with two adjacent broken bars, and so on rotor containing four bars adjacent broken.

Monitoring condition:

All signals were sampled at the same time for 18 seconds for each loading condition and ten repetitions were performed from transient to steady state of the induction motor.

- mechanical signals: five axial accelerometers were used simultaneously, with a sensitivity of 10 mV/mm/s, frequency range from 5 to 2000Hz and stainless steel housing, allowing vibration measurements in both drive end (DE) and non-drive end (NDE) sides of the motor, axially or radially, in the horizontal or vertical directions.

- electrical signals: the currents were measured by alternating current probes, which correspond to precision meters, with a capacity of up to 50ARMS, with an output voltage of 10 mV/A, corresponding to the Yokogawa 96033 model. The voltages were measured directly at the induction terminals using voltage points of the oscilloscope and the manufacturer Yokogawa.

Data Set Overview:

-          Three-phase Voltage

-          Three-phase Current

-          Five Vibration Signals

An inductive power transfer (IPT) system is envisaged as the best solution to conveniently charge electric vehicles (EVs). While stationary IPT systems are becoming commercialized, significant research is being conducted to address the challenges related to dynamic IPT systems. Dynamic or in-motion IPT systems require a fully electrified roadway with embedded inductive couplers with accompanying circuitry. The large number of electronic components required, however, increases the system complexity, reducing the reliability and economic viability of dynamic IPT systems proposed to-date.

This paper proposes a reduced switch count WEtype inverter topology that employs one DC source, nine IGBTs, and one AC-switch comprising of two antiparallel IGBTs, and two capacitors. It is capable of generating 1.5 times boosted 13- level output voltage and employs modified Nearest Level Control (NLC), which considers both zero states. An algorithm based on redundant states controls the voltage across the auxiliary DClink at Vdc/2.

Globally building sector energy consumption is increasing rapidly. Improving building energy efficiency is essential for sustainability. Load monitoring provides detailed consumption feedback to enable consumers to save energy. Non-Intrusive Load Monitoring (NILM) is a cost-effective way to identify individual appliance energy consumption from aggregate energy consumption.

Instructions: 

There are 6 files corresponding to aggregate energy data collected at 6 different source voltages from 190V to 240V.The features in the data are Voltage,Current, Active Power(P), Apparent Power(S), Reactive Power(Q), Power Factor, Phase angle, Class, Resistance, Pdiff, Sdiff, Qdiff, Rdiff, Device.It is a continuous time series data collected at 10 Hz from automated data collection setup. Collect aggregate data of 7 home appliances namely Geyser, Kettle, Mixer, Oven, Fan, Air Purifier and Vacuum Cleaner. The Class column contains a numeric value whose binary equivalent represents the configuration of appliance in ON/OFF state that results the aggregate data. The numbers are grey code sequence, allowing only one device change state at any time. Device column contains the label of the event happened in data such as Geyser in ON state event labelled as GON. Fan in OFF state event is FOFF. The No events data are labelled as NN. Resistance column is calculated feature, is the ratio of voltage and current. Other features such as Pdiff, Sdiff, Qdiff and Rdiff are the single difference values of P, S,Q and R features.
