IEC 60700-1:2015/AMD1:2021

IEC 60700-1:2015/AMD1:2021 is a targeted amendment to Thyristor valves for high voltage direct current (HVDC) power transmission - Part 1: Electrical testing, intended to support accurate electrical testing and technical evaluation for HVDC valve systems. It is relevant where engineering teams, laboratories, and compliance groups need a reliable compliance reference for verification activities, documented evaluation, and procurement review. As a supporting document connected to IEC 60700-1:2015, it helps maintain operational consistency across testing workflows and conformity assessment preparation.

What is IEC 60700-1:2015/AMD1:2021?

This amendment modifies the parent document IEC 60700-1:2015 and should be used as a technical update within the broader framework for electrical testing of thyristor valves used in HVDC power transmission. Its purpose is to refine or adjust the underlying testing requirements rather than stand alone as a complete specification. For organizations managing engineering documentation, technical validation, or laboratory evaluation, IEC 60700-1:2015/AMD1:2021 provides an important reference point for keeping test methods and compliance workflows aligned with the latest published changes.

Applications of IEC 60700-1:2015/AMD1:2021

IEC 60700-1:2015/AMD1:2021 is typically used in HVDC project environments where thyristor valve assemblies undergo electrical testing as part of product evaluation, factory verification, or acceptance-related procedures. It is relevant to manufacturers, test laboratories, utilities, contractors, and specification writers involved in high-voltage power transmission equipment. The amendment can also support technical review during procurement, especially when contracts require evidence of conformity with the parent testing standard and its updates. In practice, it helps teams apply consistent test expectations across documentation and assessment activities.

Why is IEC 60700-1:2015/AMD1:2021 important?

For HVDC equipment programs, this amendment matters because even small changes to electrical testing guidance can affect safety margins, test consistency, and conformity assessment outcomes. Using IEC 60700-1:2015/AMD1:2021 alongside the parent standard can help reduce ambiguity during engineering validation and improve confidence in documented results. It is also useful for risk management, quality assurance, and regulatory preparation when teams need a clear technical basis for inspection, testing, and acceptance decisions. For procurement and compliance workflows, it supports more defensible technical assessment and specification control.

• Supports electrical testing of thyristor valves used in HVDC power transmission.
• Functions as an amendment to IEC 60700-1:2015, not as a standalone replacement.
• Helps align laboratory evaluation, documentation, and conformity assessment activities.
• Useful for engineering teams, utilities, manufacturers, and procurement reviewers.
• Assists with technical validation, quality workflows, and controlled specification updates.
