GRACIDA-AGUIRRE, M.  e  CALLEJA, H.. Voltage monitoring instrument with fast-transients capture capability. J. appl. res. technol [online]. 2003, vol.1, n.3, pp.194-201. ISSN 2448-6736.

A monitoring instrument aimed at recording the voltage levels at residential installations is described. Its main feature is the capability ot recording short transients, lasting less than one cycle, while requiring a rather modest amount of memory for long monitoring periods. The instrument uses synchronous sampling of the voltage waveform, and its response to outages has been optimized.
