My Client in Canada has an unusual request to connect a small 400 V, 2000 kVA generator to a 44 kV grid using a pad mounted step up transformer 0.4/44 kV WYE/DELTA with both 400 V and 44 kV cable terminations located inside a metal enclosure bolted onto the transformer.
The transformer enclosure should also somehow accommodate fuses on the HV side (probably hidden somewhere behind HV terminals and accessible from the top).
I can’t seem to locate any manufacturers who would can make CSA (or ANSI) approved pad mounted transformers at 44 kV level (or 46 kV), and especially not with fuse assemblies built-in. Transformer manufacturers I contacted would go with pad mounted design with or without fuse up to 38 kV max (usually up to only 34.5 kV). Over 38 kV only transformers with external top or side mounted bushings would be available. Does someone have an idea how to approach this? Thank you in advance.
