IEC 60700-2:2016 defines terms for thyristor valves for high-voltage direct current (HVDC) power transmission with line commutated converters most commonly based on three-phase bridge connections for the conversion from AC to DC and vice versa.

IEC 60747-6:2016 provides standards for the following types of discrete semiconductor devices:
- reverse-blocking triode thyristors;
- reverse-conducting (triode) thyristors;
- bidirectional triodethyristors (triacs);
- turn-off thyristors.
This edition includes the following significant technical changes with respect to the previous edition:
a) Clauses 3, 4, 5, 6, and 7 were amended with some deletions of information no longer in use or already included in other parts of the IEC 60747 ser...view more

This International Standard defines routine and type tests on thyristor valves used in thyristor
controlled series capacitor (TCSC) installations for AC power transmission.
The tests specified in this International Standard are based on air insulated valves operating
in capacitive boost mode or bypass mode. For other types of valve and for a valve operating
in inductive boost mode, the test requirements and acceptance criteria are agreed between
purchaser and supplier.

This part of IEC 60700 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 tests specified in this standard are based on air insulated valves. For other types of valves,
the test requirements and acceptance criteria can be agreed.

This International Standard defines type, production and optional tests on thyristor valves used in thyristor controlled reactors (TCR), thyristor switched reactors (TSR) and thyristor switched capacitors (TSC) forming part of static VAR compensators (SVC) for power system applications. The requirements of the standard apply both to single valve units (one phase) and to multiple valve units (several phases). Clauses 4 to 7 detail the type tests, i.e. tests which are carried out to verify that th...view more
