Typically this can occur when evaluating foot impedance computations for summer seasonal conditions.

The computation of foot impedance used in the evaluation of safe touch and step voltage values is the benchmark used in astm g57 IEEE Grounding on a Repowering Project with Limited Information: No items in cart. Search book astm g57 Enter keywords for book title search.

In addition, the grounding system must be designed under tight budget constraints and schedules as these repowering projects have short project lifecycles. In addition the electronic files may not be downloaded or distributed astm g57 over computer networks or otherwise.
