IEEE 664 The basic engineering approach to the control of vibration of overhead conductors is to compare the totalpower dissipation characteristics of vibration dampers and of the conductor itself to the projected windpower input to the conductor span. The wind power input can be estimated by using the techniques describedin [B1],[B2], and [B5].’ The power lost to self-damping in conventional conductors can be obtained usingthe methods described in IEEE Std 563-1978 [B7]. For a given conductor span at a given frequency andexcitation level, the difference between the wind power input and the conductor self-damping is the amountof power that ideally should be dissipated by the vibration damper [B10].
This guide is written to quantify the power dissipation characteristics of vibration dampers by applying anappropriate laboratory test method. The four test methods provided in this guide are: Inverse Standing WaveRatio (ISWR), Power, Decay, and Forced Response. lt is understood that the methods outlined here may notbe all inclusive and that the development of new methodologies is strongly encouraged. Since there is a vari-ety of damping devices currently commercially available, the appropriateness of the method selected and thequalification/disqualification of a given product are left strictly up to the end user.
In addition, this document is intended as a guide to the practical and economical principal methods that havebeen usefully applied in the past, and which merit consideration by those contemplating the measurement ofthe dissipation characteristics of vibration dampers. A more detailed survey of previously used methods,along with a discussion of errors associated with the laboratory testing environment, can be found in [B9].
This clause will outline the methods and procedures for tests using a conductor span [B11],[B12]. The gen-eral apparatus described here will apply to the ISWR, Power, and Decay methods. The methodology andprocedures for the Forced Response method do not require the use of a conductor test span and are providedin clause 5.IEEE 664 pdf download.
