説明
<p>The relationship between “surge impedance”, which is defined as the ratio between the maximum transient voltage and current in a time domain, and “impedance” in the frequency domain is discussed based on a set of measured transient responses of an earthing circuit in a traction substation. The frequency characteristics of the results are numerically determined using linearized Laplace transform (LLT). The results indicate that the rise time of the injected impulse current is a key parameter that determines the relationship between the surge impedance and the impedance in a frequency domain. The investigation shows that the surge impedance which can be easily obtainable in a field test is useful for characterizing the transient grounding characteristic by appropriately utilizing the relationship.</p>
