This International Standard applies to self-commutated converter valves, for use in a threephase bridge voltage sourced converter (VSC) for high voltage DC power transmission or as part of a back-to-back link, and to dynamic braking valves. It is restricted to electrical type and production tests.

This document can be used as a guide for testing of high-voltage VSC valves used in energy storage systems (ESS).

The tests specified in this document are based on air insulated valves. The test requirements and acceptance criteria can be used for guidance to specify the electrical type and production tests of other types of valves.
