Tiger Ring Main Unit
(OP)
I am trying to find out what manufacturer/type of fuses were used in the Tiger ring main units (11kV). I am doing a protection coordination where I have come across one (90A).
Thanks
Thanks

Try contacting the 11kV network design dept of your local electricity company if you are UK based. The Tiger FRMU is still used in many areas

I've dug up the following info which may help solve your problem
We used 90A Fuses ESI REF IIOIL10 in FRUM'S on 100KVA TX'S. Manufacture ref as follows
B.S.= OQGRN 90A G.E.C = KEMXO 90A & Brush OHGMA 90A
The max size LV fuse we would fit to discriminate was 600A
The HV fuse links were to ESI Standard 12-8

Sorry Redwing it should read 1000kVA not 100kVA!
