Designing a power system of 420 kv
Trench to supply world''s first 420 kV dry-type shunt reactor
Trench will be supplying the world''s first 420 kV dry-type shunt reactor to a German Transmission System Operator. The unit is scheduled for delivery in March 2021. While Trench say their technology allows them to produce dry-type shunt reactors at up to 550 kV voltage, this 420 kV unit will be the highest rated unit sold so far.
