37、his standard applies to thyristor valves with metal oxide surge arresters directly connected between the valve terminals, for use in a line commutated converter for high voltage d.c. power transmission or as part of a back-to-back link. It is restricted to electrical type and production tests. The t
38、ests specified in this standard are based on air insulated valves. For other types of valves, the test requirements and acceptance criteria must be agreed. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this
