摘要： A method of testing a fuse in apparatus for monitoring electrical insulation surrounding first and second electrical conductors in a cable, the fuse being connected to the conductors, comprises: applying an electrical signal, with respect to a reference, to the fuse from a source; obtaining a value for the resistance of the insulation with respect to the reference; determining if the resistance value is greater than a fuse test resistance threshold and, if it is, causing the application of the signal to cease; and monitoring the decay of the signal to determine if the time for it to decay below a set value exceeds a set time limit, indicative of the fuse being satisfactory, or is less than the limit indicative of the fuse being blown.
