Voltage sourced converter (VSC) valves for static synchronous compensator (STATCOM). Electrical Testing1 Scope This document 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.
