A model driven approach can meaningfully reduce the amount and the complexity of the required tests. This is very important when in field experimental activities are required. A typical example of this situation is the metrological assessment of the instrument transformer (IT) for medium and high voltage applications. The aim of this paper is to present a different approach to the instrument transformer modeling. This proposal leads to an analysis of the instrument transformer that is independent by the waveform shape of the voltage applied to its primary and simply based on the measurement of the input and output signals. In this paper an experimental procedure for the identification of the model parameters of a voltage IT (VT) at the AC-mains frequency is presented and discussed. Finally, the proposed model has been simulated by using the parameters experimentally evaluated. The simulation results have been compared with those obtained through a conventional calibration procedure.","PeriodicalId":420824,"journal":{"name":"2011 IEEE International Workshop on Applied Measurements for Power Systems (AMPS)","volume":"8 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130336824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A novel adaptive magnetic modulation technology with double feedback properties is applied to modulate the current. And a simplified demodulation method, involving an 8th order low pass Butterworth filter is designed to measure the current. One typical application of this method is the detection of residual current for type B RCD (residual current device) complying with IEC60947-2, in which the residual current of sinusoidal AC, pulsating DC and smooth DC should be detected to protect person and machine. The type B RCD with the current sensing method characterizes wide current sensing range, low power consumption and high current measurement accuracy.","PeriodicalId":420824,"journal":{"name":"2011 IEEE International Workshop on Applied Measurements for Power Systems (AMPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133583099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The IEC61850 defines two different protocols for distributing time in Station and Process Bus: SNTP and IEEE1588 PTP. The two protocols have almost different time representations and synchronization schemes. When an old IEC61850 device with SNTP has to be integrated into new substations with PTP-compliant network infrastructure, time gateways may be required. The paper discusses the time synchronization concerns in a typical Substation Automation System and analyzes the performance of a compact Time Gateway; it is a transparent, two-ports, device which is inserted in the last network link between the switch and the end device. The tests have been carried out by means of an embedded prototype based on FPGA. The experimental results show the applicability of the Time Gateway concepts, giving useful hints on the trade off between synchronization accuracy and device complexity.","PeriodicalId":420824,"journal":{"name":"2011 IEEE International Workshop on Applied Measurements for Power Systems (AMPS)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121111367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The flexibility of the generated input signals for which the PMU performance is assessed represents a novel contribution of the designed setup. Transient disturbances modeled by mathematical functions or extracted from simulated networks within DigSILENT PowerFactory software are converted to COMTRADE files and uploaded into two signal generators in order to build relevant analogue waveforms for analyzing Phasor Measurement Units (PMUs) steady state and transient behavior. A novel characteristic of the design consists of the automated generating, acquisition and analysis procedure capable of processing the large quantity of results on which the steady state and transient performance assessment of WAMS is based. The assessment has revealed some equipment introduced phase shift errors, but their cause has been identified and overcome through the comparison of qualitative parameters of the input and output signals.","PeriodicalId":420824,"journal":{"name":"2011 IEEE International Workshop on Applied Measurements for Power Systems (AMPS)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128708061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, bushing failures are responsible for a very significant number of transformer breakdowns. This encouraged the research on continuous monitoring systems allowing the detection of incipient faults and thus the implementation of Condition Based Maintenance (CBM) techniques to power transformer bushings. Many on-line diagnostic techniques can be found in literature; however most part of them suffers from some limitations or high complexity. The authors have previously proposed a novel method allowing the early fault detection through the superimposition of a high frequency signal across the bushing tap and ground. In this paper it will be shown how this monitoring technique can be implemented.
