MIL-T-594B

Abstract

This specification covers the Test Sets (growlers) for locating defective circuits in armatures or stators in rotating electrical machines. <br>Test Sets shall be of the following types, as specified (see <a>6.1</a> and <a>6.2</a>): <br>Type A - External Test Set for armatures from &#189; to 4 inches in diameter. <br>Type B - External Test Set for armatures from 2-&#189; to 6 inches in diameter. <br>Type C - External/internal Test Set for armatures 6 to 12 inches in diameter and stators from 2-&#189; to 12 inches in diameter. <br>Type D - External/internal Test Set for armatures 2 inches and larger in diameter and stators 6 inches and larger in diameter. <b><u>Intended Use:</u></b> The test sets covered by the specification are intended for use in sheltered military environments, onboard ships and at land based installations. The individual test sets limitations is established by its type classification (see <a>1.2</a>) as follows: (a) Type A - For use in locating short circuits, open circuits, and ground in light duty, small armatures of rotating electrical machinery. (b) Type B - For use in locating short circuits, open circuits, and ground in heavy duty, small armatures, including engine starting motor armatures and battery charging generator armatures of rotating electrical machinery. (c) Type C - For use in locating short circuits, and open circuits in medium size armatures and stators of rotating electrical machinery. (d) Type D - For use in locating short circuits and open circuits in large size armatures and starors of rotating electrical machinery. <br>
