What is BS 4999-145 - Specification for winding termination of rotating electrical machines about?

BS 4999-145 is a British Standard. BS 4999-145 specifies types of and performance requirements for winding terminations for rotating electrical machines rated for a.c. voltages up to 15 kV r.m.s. Minimum creepage and clearance distances appropriate to the rated voltages are also specified. BS 4999-145 does not specify requirements for the ability of the terminations of the following machines to withstand a high energy fault: Machines rated for voltages up to and including 660 V, which it is assumed, would be protected by fuses or other energy limiting devices Machines rated for voltages of 1,100 V and above either protected by fuses or other energy limiting devices or intended for operation on a system where the nominal short-circuit capacity is lower than the relevant value given in BS 4999-145 .
