<br /> <br /> <br /> IE<br /> Winding Resistance<br /> Testing of Motors<br /> Winding resistance measurements detect various faults in motors and transformers: shorted<br /> turns, loose connections, broken strands and malfunctioning tap changer mechanisms. Winding<br /> resistance measurements detect problems in motors which other tests may not find.<br /> T<br /> hese problems include partial or fully shorted coils, poor A higher test voltage will overcome the inductance more quickly (up<br /> crimps or connections, imbalance between phases (improper to 50 times faster than a normal low-resistance meter). A regular<br /> turns on phases) and incorrect coil (phasing) connections. multimeter cannot perform winding resistance measurements.<br /> Studies conducted by IEEE and the Electric Power Research Institute Megger’s MTO106 provides up to 6 A of test current and 48 V of<br /> (EPRI) on electric rotating mac<a title="2019 - Industrial Electrix Issue 4 2019 page 1" href="http://viewer.zmags.com/publication/a0bada79?page=1"> </a> <a title="2019 - Industrial Electrix Issue 4 2019 page 2" href="http://viewer.zmags.com/publication/a0bada79?page=2"> </a> <a title="2019 - Industrial Electrix Issue 4 2019 page 3" href="http://viewer.zmags.com/publication/a0bada79?page=3"> IE Winding Resistance Testing of Motors Windi</a> <a title="2019 - Industrial Electrix Issue 4 2019 page 4" href="http://viewer.zmags.com/publication/a0bada79?page=4"> 8 22 28 30 2 CONTENTS 4th Quarter 2019 • </a> <a title="2019 - Industrial Electrix Issue 4 2019 page 5" href="http://viewer.zmags.com/publication/a0bada79?page=5"> COVER STORY FLIR IS CONTINUOUSLY IMPROVING THERMA</a> <a title="2019 - Industrial Electrix Issue 4 2019 page 6" href="http://viewer.zmags.com/publication/a0bada79?page=6"> ARC FLASH The Physics of Arcing Faults and h</a> <a title="2019 - Industrial Electrix Issue 4 2019 page 7" href="http://viewer.zmags.com/publication/a0bada79?page=7"> • The electrical system maintainers are likely t</a> <a title="2019 - Industrial Electrix Issue 4 2019 page 8" href="http://viewer.zmags.com/publication/a0bada79?page=8"> ARC FLASH Continued from page 5 ADMINISTRATIVE C</a> <a title="2019 - Industrial Electrix Issue 4 2019 page 9" href="http://viewer.zmags.com/publication/a0bada79?page=9"> Enhanced resolution across all levels.
