Requirements for structural scheme and features unit for radio frequency interference limits testing of high-voltage insulators are considered.
The basic scheme of developed unit and method for radio frequency interference limits testing of high-voltage insulators according to intergovernmental standards are described.
Minimum unit parameters K+A=22 dB (mode 0,5 MHz) and K+A=21 dB (mode 1 MHz), which measurement is performed not separately but as a sum immediately, providing high stability results, are achieved.
The data of measuring the level of external interference (noise of the unit) and the conditions of its use are given.
Materials of the article may be useful for the development of high voltage equipment, oriented to the requirements of international standards.
