1. Summarize:Electric quantity transducer is a measuring instrument that it makes measurand electric quantity (AC Current/Voltage Active Power Reactive Power Active Energy Reactive Energy Power Line Frequency.Phase Angle Power Factor DC Current/Voltage) turn into DC current or voltage output that accroding to proportional linearity . It widely applied to electric measurement autocontrol and system altitude that in electric power Coal metallurgy railway and so on.Applied Standards & Rules Measuring and conversion IEC 688 / 1992 - 04 Dielectrical strength IEC 688 2KVac / 1 min.
Surge and Impulse test ANSI C37.90 / 1989
IEC 255-3 (1989) 4KV 1.2 x 50 us Current transducers convert AC input into load independent DC current & voltage output signal. This signal is highly accurate & proportionally linear to the AC input. GPA versions convert the AC sinusoidal waveforms to linear DC output calibrated to the RMS value.2.Models: GPA single phase current
