JOIXT DEVELOPMENT AND LOW FREQUENCY INDUCTION 229 



Bibliography 



Many features of power system design, operation and stability, as well as many 

 features of the telephone system, have a bearing on low-frequency mduction. It, 

 therefore has appeared impracticable to include a complete bibliography but the 

 following' references include the more important reports and articles on this subject.
