  • Fuel Cell Voltage Monitoring Considerations

    Knowing what’s happening inside a fuel cell is a critical function, especially as fuel cells are continuing to be developed. One important aspect of this is to measure the voltageof each cell in a stack. Although this may sound trivial, it can be more complex and more expensive than it may at first appear due to high voltages, high channel counts,communication types, etc. There ...

  • Full waveform data display

    FlashRES resistivity meter displays full current and voltage data when the system is collecting these data. The real time read out of the data effectively helps operator to monitor the data quality. In case the data quality Q factor drops in value, the operator can pause the data collection process and check the background, contact and instrument noise. Displa full waveforms thus protect ...

  • IP data collection

    FlashRES resistivity meter collects 4*N voltages for each AB current injection. When operator sets the instrument collect IP data, the system will default the on time equals to the off time. ZZ finds sometime operators need customise their IP windows, thus FlashRES records all the data and this enables operators to form their own IP windows data with their own window size criteria. ...

  • The amount of data FlashRES can collect in one hour

    FlashRES can collect over 62k data points in one hour. Some of the 62k data however may not be useful to the operator. Operator needs assess the geological data to find which part of the resistivity data is less useful. ZZ provides data filtering software to filter unwanted data points for operators. FlashRES resistivity meter records the whole three curves for each current pair. Users can ...

  • Characterisation of power quality disturbances based on wavelet transforms

    This paper presents a new technique for detecting and characterising disturbances in power systems based on wavelet transforms. The voltage signal under investigation is often corrupted by noises, therefore the voltage signal is first denoised using wavelet thresholding and then wavelet transform is applied to the denoised signal. Using the first-level detail wavelet coefficients, the voltage ...

  • Reactive power compensation strategies for wind generation in distribution systems: a power quality approach

    This paper studies the impact on the voltage profile of wind energy based generators connected to distribution power systems. Voltage fluctuations arise in distribution levels including noncontrollable primary energy sources because of their corresponding active power injection variations. A number of reactive power strategies have been analysed and compared focusing on the voltage fluctuation ...

  • Electrical conduction of calf-thymus DNA molecules

    We present theoretical calculations to explain the behaviour of electrical conduction in calf-thymus DNA molecules trapped between a gap of 10 nm Au electrodes. Our work further explains the experimental I-V data reported for these DNA molecules that shows both large electrical hysteresis and voltage gap. We attribute their data to energy conservation within the molecules and electrons transfer ...

  • Power quality problem mitigation by unified power quality conditioner: an adaptive hysteresis control technique

    An adaptive hysteresis current and voltage control technique for controlling Unified Power Quality Conditioner (UPQC) is proposed in this paper. The novelty of the proposed method is the series and shunt active power filters (APF) present in the UPQC has been controlled by the separate adaptive controllers for reducing the voltage and current perturbations. Here, the adaptive control technique ...

  • Determination of the mechanism behind the organic magnetoresistance (OMAR) effect by using impedance spectroscopy

    We investigated the organic magnetoresistance (OMAR) mechanism in poly(3–hexylthiophene–2,5–diyl) (P3HT)–based diodes, by using impedance spectroscopy. We have prepared layered structures consisting of indium tin oxide, poly(3,4–ethylenedioxythiophene):poly(styrenesulphonate) (PEDOT:PSS), P3HT and aluminium and measured the bias voltage dependence of the OMAR and of the impedance spectra. The ...

  • Metallic nanoparticles for application in electronic non-volatile memories

    Nanoparticle memories have appeared during last years as a possible solution to overcome the scaling issue of electronic nonvolatile memories. Ultimately, we are looking for nanoparticle memories to significantly decrease the voltage needed to write/erase the memory without compromising its retention characteristics. As an alternative to semiconductor nanoparticles which have been intensively ...

  • Security, trust, and QoS in next-generation control and communication for large power systems

    The present communication architecture supporting control of the electric power grid makes it difficult to use the wealth of data collected at high rates in substations, retarding their use in new applications for controlling the grid. A flexible, real-time data network would make it possible to use these data for many more control and protection applications, potentially increasing the grid's ...
