The capability of electrical and electronic systems, equipment, and devices to operate in their intended electromagnetic environment within a defined margin of safety, and at design levels or performance, without suffering or causing unacceptable degradation as a result of electromagnetic interference.
In condition to provide a function of inadmissible radio noise, at the stage of a choice in order to choose a point of a dislocation it’s essential to carry out the experimental analysis of an electromagnetic environment.
So far as the sensitivity of the existing measuring equipment is much lower than the sensitivity of the HSR radio-receiving device, according to all standard techniques, the results received from carrying out the experimental analysis of electromagnetic environment at the point of dislocation are incomplete. Therefore the data of an influence of electromagnetic environment on high can be obtained not only experimentally, but also by calculations.
This problem is particularly acute concerning overhead power transmission lines (PTL), the level of a man-made noise from PTL is impossible to capture on the point of HSR dislocation by the measuring equipment.
Therefore in order to receive the fuller results on electromagnetic environment it is necessary to carry out a settlement and experimental assessment of influence of PTL on HSR.
At the first stage it is essential to take measurements of levels of intensity of the electric field of a man-made noise according to GOST 22012-82.
The measured level of a man-made noise needs to be recalculated in the HSR the dislocation point and compared to reference sensitivity of HSR. Then there must be a conclusion of the influence of PTL on HSR or lack of such influence.
