General requirements for rotating electrical machines -- Specification for winding terminations
This part of this British Standard 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.
This standard does not specify requirements for the ability of the terminations of the following machines to withstand a high energy fault:
The standard applies to terminals, terminal boxes and terminal enclosures, but it does not specify requirements for flameproof terminal enclosures.
The choice of a particular termination will be largely governed by the service and environmental conditions, but the standard is also relevant to the various types of cables normally used, including aluminium and, where applicable, cable sealing and dividing boxes. It is outside the scope of this British Standard to cover external supply cables in detail, but insofar as the design of the terminals is concerned, essential data are listed.
Winding terminations for small power machines having rated outputs up to and including 0.75 kW or kV·A per 1 000 r/min, such as those specified in BS 5000-11, are not covered by this standard.
NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
