Abstract
Improved grounding can be a cost-effective method to improve power quality by reducing the number of lightning flashovers on shielded overhead transmission lines. Improvements can be valued against benchmark values of cost per avoided customer momentary dip. Effectiveness of improvements can vary widely because the local soil resistivity varies with a wide statistical distribution. A portable impulse Zed-Meter00AE; can be used to measure the local transient response of transmission tower ground electrodes.
