Hi Moshe:

I checked the Littlefuse web site and found a "medium voltage" fuse rated 14,400 volts, 0.5 amp and up. This fuse is 12 inches long, 1-5/8 inches in diameter! HUGE! (Of course, its interrupt rating is 80,000 amperes.) I suspect you don't want something this big. I also suspect you don't have 80,000 amperes to interrupt. So, without knowing anything about your circuit or applciation... * Check out the various fuse manufacturers. * If the 10 kV is derived from a lower voltage, fuse the low voltage side. * Use a low-voltage side electronic overcurrent detector. * Put a low-voltage current sense in the grounded return leg to the transformer. Use the output to control the primary.
