The closest active standards are (International Electrotechnical Vocabulary) or IEC 60995 (which deals with high-voltage direct current (HVDC) thyristor valves). Given your mention of a “patched” PDF, it is highly likely you are referring to a cracked, modified, or otherwise unofficial version of a document—possibly a typo for IEC 60995 , IEC 60050-195 , or a misremembered local standard.
: Users may inadvertently type "600995" instead of "60099-5," a common mistake given the document's high numeric density. The term "patched" might simply be an accidental addition or a misunderstanding. iec 600995 pdf patched
The primary purpose of the document is to provide a structured methodology for choosing, placing, and coordinating surge arresters. Surge arresters protect costly electrical substation equipment (such as power transformers and switchgear) from transient overvoltages caused by lightning strikes or internal network switching events. The standard applies to three main design categories: The term "patched" might simply be an accidental
to show exactly what was changed or "patched" from previous versions. Consolidated Version: IEC 60099-5:1996+AMD1:1999 CSV The standard applies to three main design categories:
The standard is the globally recognized definitive framework for the selection and application of surge arresters in three-phase power systems operating above 1 kV. In high-voltage engineering, this document dictates how utilities and electrical engineers protect critical transformer and substation infrastructure from catastrophic lightning and switching overvoltages.
: This is the more concerning interpretation. In online forums and file-sharing communities, "patched" often refers to a PDF file that has been deliberately altered to bypass protections, remove watermarks, or otherwise circumvent copyright controls.
