Mining accidents have occurred since the early days of mining. Therewere a total of 525 mining disasters (incidents with five or more fatalities) in both coal and metal/nonmetal mines from 1900 through 2007 in the United States, resulting in 12,823 fatalities. Most of these disasters involve mine rescue teams, which are specially trained to perform search(More)

An essential step toward the development of an intelligent substation is to provide self-diagnosing capability at the equipment level. Transformers, circuit breakers and other substation equipment should be enabled to detect their potential failures and make life expectancy prediction without human interference. This paper focuses on the development of an(More)
A new sensor technology based on Electromagnetic Acoustic Transducers (EMAT) for nondestructive testing is developed and used for real-time fault recognition of energized overhead transmission lines. The fault detection is achieved by analysis of the reflected signatures from broken strands on the transmission line. Reflected waves received by the EMAT are(More)
