The following minimal editorial changes were made to this document.
---Added formula number;
--- Add "Note 3" in 3.7 (see 3.7);
--- Add "Note" in 5.2.1 and 8.2 (see 5.2.1 and 8.2);
---Change the name of the insulation test between valve terminals and valve chamber and the insulation test between valve terminals from "AC test" to "AC voltage test"
(See Table 2, 7.3.1, 8.3.1 and 8.3.2.1);
--- Correct the "maintain test voltage Utv11min" in the AC voltage insulation test procedure between valve terminals to "maintain test voltage Utv1
15s”(see 8.3.1.2);
--- Change the text symbol "SIPLV" of the valve arrester operating impulse protection level to "USIPLv" to conform to the writing rules of the quantity symbol.

Thyristor Valves for Thyristor Controlled Series Capacitors (TCSC)
Electrical testing
1 Scope
This document specifies routine and type tests on thyristor valves for use in thyristor controlled series capacitor (TCSC) installations for AC transmission.
The tests specified in this document are for air-insulated valves operating in capacitive lift mode or bypass mode. For valves with other insulation types
For valves operated in the inductive lift mode, the test requirements and acceptance criteria shall be determined by agreement between the purchaser and the seller.
