Low-voltage fuses Part 4: Supplementary requirements for fuse-links for the protection of semiconduc...
For application in equipment containing semiconductor devices for circuits up to 1000 V a.c. to circuits of nominal voltages up to 1500 V d.c.
Establishes characteristics of semiconductor fuse-links in such a way that they can be replaced by other fuse-links having the same characteristics provided their dimensions are identical. Defines standard conditions for operation in service,…
Rotating electrical machines - Part 2: Methods for determining losses and efficiency of rotating ele...
Describes methods for measuring the efficiency of electrical rotating machines either by determining total losses on load or by determination of the segregated losses for air and water cooling mediums. Applies to large generators but may be used for other machines.
Method of measurement of resistivity of metallic materials
Gives procedures for determining the electrical volume resistivity and mass resistivity of solid (non-stranded) metallic conductor and resistor materials, and the resistance per unit length of solid conductors (of uniform cross-sectional area) of metallic materials. Sets out both reference and routine methods of measuring the resistivity of metallic materials.
