There will be presented results of study of short-time variations of fluxes of electrons with energies from about hundred keV up to several MeV together with very low frequency (VLF) electromagnetic wave intensity dynamics in the RELEC experiment on-board Vernov space mission. Electron fluxes were measured with number of detectors of DRGE instrument with 1 s time resolution in monitor mode and also in the “event by event” mode, which provide the detection of short increasing of fluxes at least ~15 mcs. A few detectors with axes directed normally to each other allowed detection of trapped, quasitrapped and precipitated particles. Electromagnetic waves were detected in the band 0.0001 – 40 kHz with different meters included magnetometers and complex wave probes. The satellite orbit was polar solar-synchronous that provided measurements in different areas of near Earth space including as equatorial as Polar Regions. During the time of satellite operation from July, 2014 to December, 2014 a various variations of fluxes of sub-relativistic and relativistic electrons were detected on different time scales from dozens microseconds to minutes. Among them were as well-known precipitation from inner and outer belts as unexpected electron flux increasing at the Slot, at low altitudes and at the Polar Cap area. The wave-particle interaction as possible reason of such variations is discussed.
