This part of IEC also applies to insulator strings and insulator sets of similar design when used in substations. To determine the tests which are applicable to pin insulators, reference should be made to the cross-reference table table 1. The applicable sample tests are performed on the samples El or E2 as indicated in the cross-reference table. A method for comparing type and sample test results is given in annex A. The sizes of these samples shall be determined in accordance with subclause 8. NOTE – For certain types of insulators made from ceramic material an ultrasonic test after the mechanical routine test may be useful for detecting hidden defects in the insulating material.

Translation of “IEC 60383” in English
On the core of other solid core insulators single spots without glaze shall not exceed 25 mm2. The applicable sample tests are performed on 6083 samples El or E2 as indicated in the cross-reference table. Report — artificial pollution tests on high-voltage insulators iec 60383 be used on a.
Pin insulators The following tests are applicable to pin insulators. Certain tests are applicable only to certain classes of insulator or materials. The meaning of equivalent design is given in the relevant iec 60383 when applicable. Furthermore, the total number of pinholes on the insulator unit shall not exceed: An example of a class A insulator is a long rod insulator with external fittings.
The sample tests shall be performed in the order indicated below; however, it is possible to carry out the tests which apply only to sample Iec 60383 or E2 before those which apply to the other sample, after having carried out those tests which apply to both samples. When the change affects only certain characteristics, only the test s relevant to these characteristics need to be repeated.
However, in any area of 50 mm iec 60383 10 mm the number of pinholes shall not exceed The applicable routine tests shall be performed on every insulator Mounting arrangements specific to pin insulators are given in clause For mechanical tests, the certificate shall be valid for ten years from the date of issue.

These tests are not intended to be mandatory tests on insulators whether supplied iec 60383 or as strings or as sets. It may be regarded as a provisional standard for insulator strings and insulator sets for use on d. These tests and characteristics are intended to give a common base to designers, users and suppliers of overhead lines, insulators and line equipment when definition, evaluation or verification of the electrical characteristics of such equipment is required. Moreover, it is not necessary to perform the electrical, mechanical and thermal-mechanical type tests on a new design of insulator if a valid test certificate is available on an insulator of equivalent design and same manufacturing process.
To determine the tests which are applicable to pin insulators, reference should be made to the iec 60383 table table 1. Ministry of Commerce and Industry. Enviado por Daniel flag Denunciar. Insulator iec 60383 and insulator sets for a.
Tests on composite insulators are dealt with in IEC A method for comparing type and sample test results is given in annex A.

Insulators iiec overhead lines with a nominal voltage above V – Part 2: Inclusions in the shed glaze for instance sagger dirt on the upper shed shall not exceed a total area iec 60383 25 mm2 nor shall any single inclusion lec more than 2 mm from the surface.
There is no time limit for the validity of certificates for electrical type tests. They are usually carried out on a small number of insulators and only once for a new design or manufacturing process of insulator and then subsequently repeated only when the design or manufacturing process iec 60383 changed.
Glaze defects are not allowed on the core of solid core long rod insulators.
Saudi Standards, Metrology and Quality Organization. No comparison of 603383 and sample test results can be satisfactorily made for the mechanical failing load test on pin insulators. Type tests shall be carried out only on insulators iec 60383 a lot which meets the requirements of all the relevant sample and routine tests not included in the type tests.

These subjects and relevant test methods are dealt with in the following IEC reports: This part of IEC also applies to insulator strings and insulator sets for use on d. The results of type tests are certified either by test certificates accepted by the purchaser or iec 60383 test certificates confirmed by a qualified organization. The sizes of these samples shall be determined in accordance with subclause 8.
