SELF DAMPING TEST

ON 1020 KCMIL ACCC/TW CONDUCTOR FOR COMPOSITE TECHNOLOGY CORPORATION

1.0 INTRODUCTION A Self-Damping Test was performed on an Aluminum Conductor, Composite Core – Trapezoidal Wires (ACCC/TW) conductor for Composite Technology Corporation (CTC). The conductor is 1020 kcmil with an outside diameter of 28.1 mm (1.108 inch). There are 24 aluminum trapezoidal wires stranded in 2 layers over a single composite fiberglass/carbon fiber core. The specification for the conductor is contained in Appendix A. A 795 kcmil, 28.1 mm (1.108 inch), “Drake” ACSR conductor with round wires was also tested. The testing was conducted April 20-23, 2004 by Kinectrics North America Inc. personnel at 800 Kipling Avenue, Toronto, Ontario, M8Z 6C4, Canada. Important Note: This report documents the results of Self Damping Tests performed on 1020 kcmil ACCC/TW conductor and 795 kcmil ACSR conductor. The reader should be aware that the aluminum wires are fully annealed, trapezoidally-shaped for the ACCC conductor and are hard drawn, round-shaped for the ACSR conductor. This difference has significant influence on the self-damping characteristics of the conductors. The differences are mostly a function of the shape of the aluminum wires. The core material has less influence on self-damping the conductor than the aluminum wires. The reader is cautioned that, although the results are presented together, direct comparisons should not be made and that interpretations of the self damping characteristics of each conductor should be made in the proper context.

2.0 PURPOSE OF TEST The purpose of the Self Damping Test is to measure the power dissipation characteristics of overhead conductors. The data are used to assist in the selection of aeolian vibration dampers for the cable. 3.0 TEST SET-UP The logarithmic decay method was used to perform these tests. The method is described in IEEE Std 664-1993, IEEE Std 563-1978 and the Transmission Line Reference Book – Wind-Induced Conductor Motion, EPRI 1979. The general arrangement used for the self damping test is shown in Figure 1. The test was carried out in a temperature-controlled laboratory at 22ºC ± 2ºC. The conductor was tensioned using a cantilever weight arm at one end and a hydraulic cylinder at the other end. A load-cell was placed between the hydraulic cylinder and the deadend to measure the tension in the conductor. The hydraulic cylinder was used to set the initial tension and the weight arm maintained the tension throughout the test. The conductor length between deadend clamps was approximately 32 m (105 ft). The conductor was rigidly clamped to intermediate abutments using square-faced clamps approximately the same diameter as the conductor. The clamping arrangement minimized the loss of vibration energy from of the span. An electromagnetic shaker was positioned near one end on the test span. A function generator providing a sinusoidal output controlled the electromagnetic shaker. An accelerometer measured the free-loop vibration amplitude of the conductor at mid-span. A quick release mechanism was used to detach the conductor from the shaker with minimal disturbances. A digital acquisition system recorded the output from the accelerometer. The calibratable instruments used in the test are listed in Appendix B. 4.0 TEST PROCEDURE Data Collection The conductors were tested at 5 tensions: 15, 20, 25, 30, and 40 percent of the conductor’s rated breaking strength (RTS). The conductor was tested several different frequencies. The frequencies tested were the closest test span resonance to the frequencies that are generated in the wind velocity range from 10-30 km/hr (6.2-18.6 mph). The relationship between frequency, wind velocity and conductor diameter is: f(Hz) = 50 X wind velocity (km/hr) / conductor diameter (mm) The phase angle between the force signal and the accelerometer’s signal was used to indicate when the conductor was at a resonant frequency. After the conductor had stabilized at the resonance for a few minutes the shaker was disconnected. The signal from the accelerometer was integrated in its amplifier so that the output of the amplifier is proportional to velocity. The velocity signal was recorded by a digital data acquisition system while the vibration of the conductor decayed.

Data Reduction The decay of the free loop velocity (Figure 2) from the test condition at the 25% RTS and 14.887 Hz is shown in Figure 2. This trace is used to illustrate the response of the conductor after being released from the shaker. The trace shows the envelope of the natural decay of the sinusoidal vibrations. Other test conditions decay at longer or shorter rates. A curve is fitted through the peak values of each cycle in the decay and is used to filter out small disturbances. The resulting fitted curve for the test condition in Figure 2 is shown in Figure 3. The peak-to-peak amplitude, Y, of the conductor was calculated from the peak velocity, V. Y = 1000*V / (π f) where Y = peak-to-peak amplitude (mm) V = peak free loop velocity (m/sec) f = frequency (Hz) The decay of the conductor was calculated from the equation of the fitted curve and is expressed in terms of logarithmic decrement. δ = 1/n ln(Yo/Yn) where:

δ = log decrement n = number of cycles Yo = peak-to-peak amplitude (mm) Yn = peak-to-peak amplitude at “n” cycles after Yo (mm) The power dissipated by the conductor’s self-damping is calculated by: P = ½ f m Vo

2 δ where:

P = power dissipated (watts per metre) f = frequency (Hz)

m = mass per unit length of the conductor (kg/m) Vo = peak loop velocity at amplitude Yo (m/sec)

δ = log decrement The power dissipation is plotted as Power versus Normalized Amplitude where: Normalized Amplitude = Y/D where Y = average peak-to-peak amplitude between Yo and Yn

= (Yo + Yn)/2 D = conductor diameter (mm)

5.0 TEST RESULTS Tables 1 to 5 show the data collected for the tests at 15, 20, 25, 30, and 40 percent RTS, respectively. Not all data are reported in the tables in order to make them a manageable size. Figures 4 to 8 show the graphs of the conductor’s power dissipation characteristics at 15, 20, 25, 30, and 40 percent RTS, respectively. The self damping of this conductor at 15% and 20% was too high to tune the vibration to a natural frequency for frequencies above 20 Hz and 25Hz, respectively. Only natural frequencies that could “locked-in” are analyzed. The self damping data for the 795 kcmil, “Drake” ACSR round wire conductor are plotted in red on Figures 1,3 and 5 for 15%, 25% and 40% RTS. The ACSR round wire conductor has a lower self-damping than the ACCC/TW. Higher self-damping is a benefit of all trapezoidal-shaped wire conductors compared to round wire conductors. This is true irrespective of the construction of the core of the conductor. Prepared by:
