POPKOV, VALERII IVANQVICH (Electrical Engineer) 



V. I. Popkov was born February 3, 1908. He graduated in 

 1930 from the Moscow Institute of Energetics. In 1932-36, he 

 worked at the All-Union Electro-Technical Institute. He began 

 working in 1943 at the Institute of Energetics of the U.S.S.R. 

 Academy of Sciences. Popkov has been a member of the Com- 

 munist Party of the Soviet Union since 1951. In 1953 he was 

 elected a Corresponding Member of the U.S.S.R. Academy of 

 Sciences. 



Popkov' s main work is in high-voltage technology and elec- 

 tric discharge in gases at high voltage, physical processes in 

 electric filters, and long-distance electric transmission.
