Research description:
Present research includes the development of an
optical diagnostic sensor for the monitoring of electric power
transformers. This has entailed the accelerated aging of transformer oil
and testing utilizing a wide variety of techniques. A recently completed
project utilized a new technology for ultrasonic inspection of ground-mat
risers, in which the acoustic impulse is electromagnetically coupled into
the conductor. Building on that same technology, a newly initiated
project, being undertaken in collaboration with two of my colleagues,
seeks a non-invasive test for broken strands in ACSR overhead transmission
lines. Doctoral research focused on the dynamics of streaming
electrification in large power transformers. Control of the cooling
system for minimization of the streaming electrification problem was also
included.
