35、39 BSI 2009 5 1 Scope This 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
36、production tests. The tests 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, consti

All normative documents are subject to revision, and parties to agreements based on this part of IEC 60700 are encouraged to investigate the possibility of applying the most recent editions of t
