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.
This standard by the National Standardization Technical Committee Insulators (SAC/TC80) centralized.

Radio interference test high-voltage insulators
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.
