IEC 62927:2017适用于自换向阀，用于静态同步补偿器（STATCOM）的电压源变换器（VSC）。它仅限于电气类型和生产测试。 本文件中规定的测试基于空气绝缘阀。对于其他类型的阀门，测试要求和验收标准由买方和供应商商定。

IEC 62927:2017 applies to self-commutated valves, for use in voltage sourced converter (VSC) for static synchronous compensator (STATCOM). It is restricted to electrical type and production tests.
The tests specified in this document are based on air insulated valves. For other types of valves, the test requirements and acceptance criteria are agreed between the purchaser and the supplier.
