Historically,
the cost of systems that operate in real time and extract performance data from
overhead transmission and distribution lines has been too high to justify
widespread adaption into transmission control systems. This project will develop a low cost, wireless sensor for the real
time monitoring of overhead transmission lines. The
sensor, developed and demonstrated in Phase I, provided real-time wireless data
with more than 99% availability. Analytical
results derived from the sensor measurements were verified using high-accuracy
field-monitoring equipment. Phase
II will involve: (1) adding
signal processing/waveform analysis capabilities, including current, voltage,
and voltage phasors; (2) engineering the product for manufacturing; (4) carrying
out additional field tests; and (5) manufacturing a first lot of devices.
Commercial Applications and other Benefits
as described by the awardee: The
device should have multifunction capability with a very low cost per function.
Commercial applications include dynamic line rating, clearance
monitoring systems, load survey systems, fault and event recording systems, and
grid monitoring for security and reliability.
