This handbook is int
7、ended to explain and establish conventions for terminology, instrumentation, methods of measurement and accepted procedures associated with the testing and evaluation of electric generators, generator sets, and related items. It is to be used in conjunction with MIL-STD-705 to determine capabilities
8、, conditions and compliance with the requirements of procurement documents. requirements for general use instruments, measurements and instrumentation, while the many specific methods of test are established in MIL-STD-705, Generator Sets, Engine-Driven, Test Methods and instructions. 2. Some test i
9、nstruments illustrated herein are no longer being manufactured and their functions have been superseded by newer types of instruments; the older types, however, are still being used in some areas and are still acceptable; therefore, their inclusion in this handbook will be continued until such time
10、as their removal will be in the Governments best interest. 3. Because this handbook is closely allied to MIL-STD-705, references from one to the other are freely used particularly from MIL-STD-705 to this document. Inspectors and testers will find need for both the handbook and standard when working
11、 with electrical power generation equipment. 4. covering engine-driven electric generators and other similar types of electric machinery, military personnel will find this handbook especially helpful as a convenient source of general information on electrical instruments and their proper use. This t
12、echnology has been documented from experience by government and industry engineers and technicians with the manufacturing, procurement and testing of electrical power generation equipment.
