IEC 60383-1:1993 pdf free download.Insulators for overhead lines with a nominal voltage above 1000 V – Part 1: Ceramic or glass insulator units for a.c. systems – Definitions, test methods and acceptance criteria.
This part of lEG 383 is divided into nine sections.
The first five sections cover general clauses, including general requirements and relevant test procedures.
Sections si to nine deal with four different types of insulators:
Section 6: Pin insulators
Section 7; Line post insulators
Section 8; String insulator units
Section 9: Insulators for overhead electric traction lines.
Sections 6, 7 and 8 begin with a cross-reference table giving the tests applicable to the insulators and the quantity of insulators to be tested.
Section 9, dealing with traction insulators, does not have a cross-reference table as traction insulators can be referenced to one of the three other types of insulator dealt wiTh by this part of IEC 383.
The user of this part need only refer to the section dealing with the type of insulator to be tested and to the general requirements and relevant test procedures contained in sections one to five.
IEC 60383-1:1993 applies to insulators of ceramic material or glass for use on a.c. overhead power lines and overhead traction lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz.
IEC 60383-1:1993 also applies to insulators for use on d.c. overhead electric traction lines.
IEC 60383-1:1993 applies to string insulator units, rigid overhead line insulators and to insulators of similar design when used in substations.
IEC 60383-1:1993 does not apply to insulators forming parts of electrical apparatus or to parts used in their construction or to post insulators which are covered by IEC 168: Tests on indoor and outdoor post insulators of ceramic material or glass for systems with nominal voltages greater than 1 000 V.
It may be regarded as a provisional standard for insulators for use on d.c. overhead power lines. PEC 438: Tests and dimensions for high-voltage d.c. insulators, gives general guidance for those insulators.
