Ground System ComponentsGround ConductorsConductorsThere are two basic criteria for groundingconductor selection:1. The physical characteristics of the conductormust be of a robust nature, sufficient forthe environment.2. The cross sectional area of the conductormust be of sufficient size, so that it shallsuccessfully conduct the maximum fault(surge) current for a period, which allowsthe operation of protection equipment (orthe dissipation of this energy).Physical CharacteristicsThe most common ground conductor is a soft drawn, stranded copper conductor.Flat copper strip / tape is also popular because it offers a large surface area. When siteconditions are corrosive towards copper (eg. sulphurous soil), a tinned copper conductoris often the first choice.In some circumstances, the maximum fault current for the installation is small. While aconductor of correspondingly small size could be used, a minimum cross section, oftenset by the governing authority or applicable Standards body (to minimize potentialdamage likely to occur from any future excavation on the site), is applied.Maximum Fault CurrentWhere higher fault conditions exist, the conductor size is determined by considering thecircumstances required to avoid fusing (melting) the conductor. The accepted industryStandard is IEEE 80, Guide for Safety in Substation Grounding.ERITECH ® Flat Strip Ground Conductor• Pure electrolytic copper• Low impedance• Lower impedance than equivalent sized round conductorPart Description DimensionsNo. H (in.)
