Summary: This standard specifies the insulator in a clean, dry laboratory on Radio Interference (RI) test procedures, measurement frequency is 0. 5MHz or 1MHz, or 0. 5MHz ~ 2MHz within a certain frequency. Operation, the insulator element radio interference characteristics may be due to environmental conditions, particularly humidity and contamination rainfall and other conditions vary. Taking into account the range of environmental conditions simulated rain reproducible test conditions specified is not feasible, therefore, the standard only provides a clean and dry insulators tests.

Foreword

This revised standard adopts IEC 60437.1997 "high-voltage insulators radio interference test" (in English). This standard and IEC 60437.1997 as compared to made the following modifications, modifications at a single vertical line (|) in which they are involved reg page Margin identified. --- Because this standard is the national standard itself, delete the first four chapters of radio disturbance tests for measuring frequency insulator about the world Rate Description Note; --- For ease of use, the CISPR18-2. 1986 test circuit and the test loop checking and calibration procedures included in this standard, Technical remain unchanged. Thus increasing the FIGS. 1 to 4 in Chapter 7, the column at 13.1 points 13.1.1 and 13.1.2 Two; --- Cited international standards of our standards. For ease of use, this standard also made the following editorial changes. a) instead of as a decimal by decimal comma ",". ","; b) "this International Standard" be replaced by "this standard"; c) Remove IEC 60437.1997 Foreword. Except in 13.1.1 and 13.1.2 13.1 added the two, the present standard and IEC 60437.1997 is identical number of clauses. The standard proposed by China Electrical Equipment Industrial Association.

1 Scope

This standard specifies the laboratory radio interference (RI) test program on a clean and dry insulators, the measurement frequency of 0.5MHz Or 1MHz, or 0.5MHz ~ 2MHz within a certain frequency range. Operation, radio interference characteristics of insulators may be due to environmental conditions, particularly rainfall and other moisture and contamination situation different Variety. Taking into account the environmental conditions to simulate changes in the scope of the provisions of reproducible test conditions is not feasible, therefore, the only provision in the standard Test on a clean, dry insulator. Note. The impacts include contamination state, including the state of the surface of the insulator in CISPR18-2 Amendment 1 below.
