空间干扰对电容式套管介质损耗因数(tanδ)测量结果影响的分析
摘要
空间干扰对现场试验中出现的电容式套管介质损耗因数tanδ可造成影响
使其偏小甚至出现负值。针对这一问题
笔者进行了分析研究
并提出了相应的建议:在现场进行电容性套管的介质损耗测量时
必须认真分析空间干扰网络的影响
以防止介质损耗因数的测量误差
保证测量结果的准确性。
Abstract
An analysis has been made in this paper on the effect of space disturbance upon capacitive bushing dielectric loss factor tanδ measurement
which appears to be smaller value than the normal
sometimes even to be a negative value
in site test.To ensure the veracity
as while as to avoid the measuring error
the effect of space disturbance should be considered necessarily in on-site capacitive bushing dielectric loss measurement.
