3 Definitions
3.1.1
test withstand voltage
This correction applies to the French text only.
3.2.3
redundant thyristor levels
Replace, on page 15, definition 3.2.3 by the following new definition:
the maximum number of thyristor levels in a thyristor valve that may be short-circuited
externally or internally during service without affecting the safe operation of the thyristor valve
as demonstrated by type tests, and which if and when exceeded, would require shutdown of
the valve to replace the failed thyristors or acceptance of increased risk of failures

60700-1 Amend. 1  IEC:2003 – 5 –
Add, on page 15 after definition 3.2.4, the following new terms and definitions:
