METHOD OF CONTROLLING TECHNICAL STATE OF HIGH-VOLTAGE ELECTRIC POWER EQUIPMENT Russian patent published in 2008 - IPC G01R31/00 

FIELD: physics.

SUBSTANCE: resonant frequencies and informative frequency strips EMP are calculated. Thus as the antennas of the electric power equipment, which radiate EMP, are examined the external vertical parts of the inputs of electric power equipment, which go beyond the limits of the conducting padding of inputs, which equalise potential distribution along the input, in the absence of the above mentioned padding at the input - the external vertical parts of the inputs of the electric power equipment limits which jut beyond the metal case. Furthermore as antennas loops - connections of inputs of electric power equipment with bus bars distributing the electric power on the substation are considered. Fixed in equivalent conditions integral power EMP in informational frequency strips of energetic spectra of EMP of vertical polarisation from the same controllable and reference electric power equipment. The conclusions about technical condition electric power equipment are done on the basis of comparisons of integrated capacities of EMP in the informative frequency strips fixed in equivalent conditions at the same controllable and reference electric power equipment.

EFFECT: expansion of opportunities and increase of reliability and informative capacity.
