In a current limiter production process involving application of a high temperature superconductor (HTSC) starting material powder onto a silver layer (1) surface and then temperature and oxygen treatment to form the HTSC (3), the novelty is that (a), prior to applying the HTSC starting material powder, the opposite surface of the silver layer is placed on a powder layer which is chemically inert wrt. the hot HTSC; and (b) a mechanical stabilisation layer (4) is applied onto at least one main surface of the composite conductor (1, 3), after forming the HTSC (3). Also claimed is a current limiter having a composite conductor (1, 3) comprising a HTSC (3) in surface contact with a non-superconductive shunt resistor of a silver layer (1) parallel to the HTSC, the novelty being that (i) the HTSC (3) has a layer thickness (d3) of less than 500 (preferably less than 300) microns, the silver layer (1) has a layer thickness (d1) of less than 25 (preferably less than 10) microns and d1/d3 = less than 1/5, preferably less than 1/10; and (ii) at least one main face of the composite conductor (1, 3) is in surface contact with a mechanical stabilisation layer (4). |
