PT protective fuse rating

PT protective fuse rating

PT protective fuse rating

(OP)
I have to connect outdoor type 600VA, 33kV/220v PT thru protective fuses at the primary to 33 kV (line to line) . The supplier has provided 24kV, Siba make outdoor type  , e=442mm ,Ia= 40kA  fuses, is it Suitable ?. Please guide me.

RE: PT protective fuse rating

If the 33kV system is effectively grounded and the PTs are all connected line-ground on the 33kV side then the 24kV fuses should be sufficient.

RE: PT protective fuse rating

PT is connected between Line to Line of 33 kV System.

RE: PT protective fuse rating

Then you must have 33kV fuses. But line-ground is a far better connection.
