For protection electric substations personnel from harmful effects of the super high voltage electric field, it is need to measure the level and time of electric field exposition of personal by using mobile electric field measurement instrument. The instrument are placed in mans helmet close to a head in area of high electric field intensity. Standards for limited vales of electric field intensity are estimated for undistorted electric field. As a conductor, the human body distorts the original electric field around the body and device shows distorted value of electric field. Investigation of level distortion by the finite element method and the experimental measurements shows that the maximum distortion appears with change of height of the person and at change parameters of foot ware soil. These parameters, height of the person and foot ware soil data should be used for design of a measurement devise and for adjustment the device before measurements. Change of other person parameters can be ignored because of very law level of changes field distortion.
