BS EN 62501:2009+A2:2017

This standard BS EN 62501:2009+A2:2017 Voltage sourced converter (VSC) valves for high-voltage direct current (HVDC) power transmission. Electrical testing is classified in these ICS categories:

• 29.240.01 Power transmission and distribution networks in general
• 29.240.99 Other equipment related to power transmission and distribution networks
• 29.200 Rectifiers. Converters. Stabilized power supply

This International Standard applies to self-commutated converter valves, for use in a three-phase bridge voltage sourced converter (VSC) 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 scope of this standard includes the electrical type and production tests of dynamic braking valves which may be used in some HVDC schemes for d.c. overvoltage limitation.

The tests specified in this standard are based on air insulated valves. For other types of valves, the test requirements and acceptance criteria Text deleted should be agreed between the purchaser and the supplier.
