Greetings All, I am currently planning to step-up from using neon-sign transformers and just recently bought an ABB potential transformer (i.e., ABB voltage transformer type VIZ-11, 120 to 14400V, 1.5 KVA). It is a two fuse type and is rated 110 BIL. Would anyone know if I can run this transformer with one output grounded? Also, I now have four neon sign transformers that I¹m wanting to sell. They are 12 KV, 60 mA, Franceformers that are in very-good and like-new condition. I¹m wanting to sell these quickly on ebay, so I¹m wondering if anyone would know what would be a reasonable asking price.

Hi Mike,Nice catch! I have single-fuse versions of this transformer. These are designed for indoor metal-clad switchgear, so they lack the large horns (and added weight) of similarly-rated outdoor potential transformers. Your dual-fuse version is very flexible. Either H1 or H2 can be grounded, so just pick one. H2 must be grounded on single-fuse versions.
