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 series, and with some necessary additions;
b) some parts of Clause 8 and Clause 9 were moved and added to Clause 7 of this third edition;
c) Clause 8 and 9 were deleted in this third edition;
d) Annex A was deleted.
This publication is to be read in conjunction with IEC 60747-1:2006.

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 the valve design meets the requirements specified. Clause 8 covers the production tests, i.e. tests which are carried out to verify proper manufacturing. Clauses 9 and 10 detail optional tests, i.e. tests additional to the type and production tests.

IEC 61954:2011 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). This edition includes the following significant technical changes with respect to the previous edition: a) Definitions of terms 'thyristor level', 'valve section', 'valve base electronics' and 'redundant thyristor levels' have been changed for clarification; b) Conditions of testing thyristor valve sections instead of a complete thyristor valve have been defined; c) The requirement has been added that if, following a type test, one thyristor level has become short-circuited, then the failed level shall be restored and this type test repeated; d) The time period of increasing the initial test voltage from 50 % to 100 % during type a.c. dielectric tests on TSC, TCR or TSR valves has been set equal to approximately 10 s; e) The duration of test voltage Uts2 during type a.c.-d.c. dielectric tests between TSC valve terminals and earth as well as the duration of test voltage Utvv2 during dielectric tests between TSC valves (for MVU only) has been changed from 30 min to 3 h; f) The reference on the number of pulses per minute of the periodic partial discharge recorded during a.c.-d.c. dielectric tests on TSC valves and exceeding the permissible level has been deleted.
