Its key objective is to enable students to select appropriate statistical tests to evaluate the significance of data obtained from psychological experiments. An important development for the third edition is that students are introduced to modern statistical packages as a useful tool for calculations, the emphasis being on understanding and interpretation.PsychometricsPsychologyStatistical methodsPsychologyResearchElectronic books.Psychometrics.PsychologyStatistical methods.PsychologyResearch.150.727Greene Judith269190D'Oliveira Manuela269191MiAaPQMiAaPQMiAaPQBOOK9910457896303321Learning to use statistical tests in psychology21133UNINA02470nam 2200361 450 99657466630331620231215120857.01-5044-7257-810.1109/IEEESTD.2021.9374151(CKB)5590000000438925(NjHacI)995590000000438925(EXLCZ)99559000000043892520231215d2021 uy 0engur|||||||||||txtrdacontentcrdamediacrrdacarrier2862-2020 - IEEE recommended practice for partial discharge measurements under ac voltage with VHF/UHF sensors during routine tests on factory and pre-molded joints of HVDC extruded cable systems up to 800 kV /IEEE[Place of publication not identified] :IEEE,2021.1 online resourceThe aim of this recommended practice is to establish a protocol for the measurement of partial discharges using ac voltages and VHF/UHF electromagnetic sensors, for quality control during routine tests on factory and pre-molded joints of high-voltage direct-current (HVDC) extruded cable systems having voltage ratings up to 800 kV. The various steps of the protocol for the measurement of partial discharges in such cables are carefully described. Details are given about the procedure for a sensor performance check, test setup preparation, and success criteria. The ultimate goal of this recommended practice is not verifying the compliance with any maximum acceptable limit of partial discharge amplitude, but rather focusing on the whole phenomenon of partial discharges, in order to assess whether critical partial discharges are present in the tested object (either a factory joint or a pre-molded joint of a HVDC extruded cable system). "Critical partial discharge" is used here to mean a discharge within the insulation of the object under test, excluding all external discharges that can be present during the ac voltage test, (e.g., corona discharges due to HV electrodes, conducting leads related to the test setup).Electric dischargesPower electronicsElectric discharges.Power electronics.537.52NjHacINjHaclDOCUMENT9965746663033162862-2020 - IEEE Recommended Practice for Partial Discharge Measurements under AC Voltage with VHF2583953UNISA
