Power supply fuse burning

[npowerthes]

Hello to all. I have a panle with a 3-phase supply from the 400V switchgear. This panel contains a pulsation controller fot the GT air intake filters. One of the glass fuses of this controller is burning evry time the GT geenrator synchronizes to the grid. Is there any instument to install in order to prevent this from happenning?
The power supply for the pulsation controller is 230VAC, taken through isolation transformer 400/230VAC.

- Could you specify "glass fuse" (provide type and link to datasheet or at least rating, size and if it is filled with sand or not)

- if the fuse is located upstream of the transformer provide transformer rating

Hi there electricuwe . It is an HRC fuse, 1A, 230VAC, located downstream of an 400/230VAC transformer, inside the cubicle, 400VA. The burning happens the time that the GT generator synchronizes.
