Definitions
- a location of a transmission line in space be known.
- regulations may require that locations of transmission lines in space be known.
- Some techniques have been used for predicting or approximating locations of transmission lines in space, such as techniques based on laser scanning using helicopters, and day-ahead forecasting based on an estimated amount of current to be passed through the transmission line, as well as previously collected data for predicted weather parameters.
- techniques are static, rather than dynamic, and do not yield a real time location of a transmission line in space based on real time measurements.
- FIG. 5 is a side view of the transmission line monitor of FIG. 1 , shown in an open position;
- FIG. 7 is an exploded top perspective view of the transmission line monitor of FIG. 1;
- FIG. 14 is a bottom perspective view of the lower non-conductive portion of FIG. 13;
- FIGS. 21 A and 21 B are schematic views respectively illustrating roll and tilt of a dynamic real time transmission line monitor installed on a transmission line, according to an embodiment of the present invention
- the cover portion 140 includes a substantially closed top side 141 and an open lower side 142.
- the open lower side 142 in one embodiment, has a perimeter shape substantially corresponding to a perimeter shape of the open upper side 122 of the base portion 120. That is, in one embodiment, the cover portion 140 has an oblong shape with substantially straight front and rear sides 143a, 143b, and rounded first and second ends 144a, 144b.
- the cover portion 140 is made of a semiconductive material, such that radio waves from the antenna 112 may penetrate through the cover portion 140 while a corona discharge is prevented or substantially prevented by the cover portion 140.
- the transmission line monitor 100 is free of corona discharge at 500kV.
- the cover portion 140 is made of ABS/PVC thermoplastic.
- a thickness t1 (see FIG. 12) of the cover portion 140 may be less than one tenth of a skin depth of the semiconductive material at which radio waves are completely blocked, where the skin depth is a function of a resistivity of the semiconductive material.
- the cover portion 140 is made of ABS/PVC thermoplastic having a thickness of about 0.125 inches.
- the tubular portion 185 has an opening 186 in which the travel bolt 105 is received.
- the keeper plate 180 further includes a cradle portion 187 which retains the transmission line 10 opposite the cradle portion 127 of the base portion 120.
- the keeper plate 180 in one embodiment, is made of aluminum, such as by casting or machining. However, the present invention is not limited thereto, and, in other embodiments, the keeper plate 180 may be made of any other suitable material.
- the present invention is not limited thereto, and, in another embodiment, at least two of the transmission line monitors 210 may be installed on separate transmission lines 10.
- Each of the dynamic real time transmission line monitors 210 includes one or more sensors 110 configured to sense in real time at least one of a temperature, a position, a current, an acceleration, a vibration, a tilt, a roll, or a distance of the transmission line 10 from a nearest object 15 (e.g., a tree or the ground) below the transmission line 10.
- the transmission line monitors 210 may be configured to send a signal containing information of a property of the transmission line 10 sensed by one or more sensors of the transmission line monitor 210 to the monitoring station 220 and/or to one another.
- the dynamic real time transmission line monitoring system 200 may include only one dynamic real time transmission line monitor 210 and the monitoring station 220, and the one transmission line monitor 210 sends a signal containing information of a property of the transmission line 10 sensed by one or more sensors of the transmission line monitor 210 to the monitoring station 220.
