| dc.description.abstract | Abstract: Protection and reliability are the
most paramount considerations in the power
system. Current measurement of distribution
lines is essential for the power and quality
evaluation purposes. The current measuring
devices are used for controlling, monitoring and
protection purposes. While the measurement of
current at an end connected to a substation can
be carried out without too much trouble,
intermediate current measurements cannot be
carried out with ease. Further instantaneous
phase angle differences need to be measured to
be able to evaluate power flow in distribution
lines. Thus, at present power loss calculations
are approximately carried out by the utility. So,
the power quality analysis, switching
operations and load transferring in distribution
lines are not much accurate. The use of a flux
concentrator and hall-effect sensor, with a filter,
has demonstrated that a sinusoidal current
waveform, with the correct phase angle, can be
obtained. The use of the device on an existing
line does not need disconnection, nor a separate
earth connection to obtain the magnitude and
phase angle of the current accurately. The data
from the transducer is transmitted to the
operator using radio signals rather than wi-fi. | en_US |
