GENERAL
A rectifier equipment comprises an assembly of silicon diodes on heat sinks together with fuse and surge voltage protection components, all suitably enclosed and a separately mounted transformer. Additional items, such as interconnections, control cubicles, switchgear, AC/DC measuring system, AC/DC busbars are included to specification when required.
For large current applications above 25kA, important advantages are gained by mounting the rectifier assembly in close association with the transformer known as ‘Rectiformer’ By combining the two units into an integral equipment (a) The space requirement is considerably reduced (d) Both preparatory & erection work at site is minimised (c) A.C. busbars connections are reduced to minimum.
