IEEE 147-2000 pdf download IEEE Standard Definitions of Terms for W aveguide Components
1.Overview
This standard applies to new procurements or major rehabilitation of rail-transit vehicles occurring on orafter the publication date of this standard. Existing rail-transit vehicles and those vehicles currently beingprocured need not comply except when specifically required by the authority having jurisdiction. Where aneed exists to maintain compatibility with existing rail-transit vehicles and to the extent defined by theauthority having jurisdiction, those portions of this standard in confict with compatibility requirements neednot be applied
1.1 Scope
This standard prescribes the electrical interfaces among the components coprising the auxiliary power sys:tems and their electrical interface with other train-borne systems. As such, this standard treats the auxiliarypower system components (e.g., static inverters and converters, ow-voltage dc power supplies. back-up battery systems, and batery chargers) as black boxes and addresses only their interface requirements. It doesnot provide standards or recommendations for the following:
Rotating machinery, such as motor alternator sets
Motive power systems or auxiliary power systems required for locomotives
Mechanical mounting or vibration isolation of equipment
Car-body wiring, branch circuits, circuit breakers, protection, and devices to interconnect theauxiliary power components with other car-borne equipment
1.2 Purpose
The purpose of this standard is to standardize the electrical input and output requirements of the auxiliarypower system components. This will be conducive to standardized designs rather than custom designs of carborne equipment utilizing the supply voltages of the auxiliary power systems. It will also aid in more clearldefining the electrical interface requirements between the major component parts that comprise the auxiliarypower systems, thus promoting their standardized design. The combined effect should increase the numberof potential suppliers and correspondingly result in reduced railcar costs.

3.1 Definitions
For the purposes of this standard, the following terms and definitions apply. The IEEE Standard Dictionaryof Electrical and Electronics Terms (B2)’ should be referenced for terms not defined in this subclause. Webster’s New Collegiate Dictionary [B5] shall otherwise apply.
3.1.1 aging factor: A quantitative factor expressing the degradation in the ability of the battery, due tousage, to deliver electrical energy under specified operating conditions such as, but not limited to, operatingambient temperature, cycling, depth of discharge, and maintenance practices.
3.1.2 authority: A geographical or political division created specifically for the purpose of providing trans-portation service.
3.1.3 authority having jurisdiction: That entity that defines the contractual (including specification)requirements for the procurement.
