Test to Grounding Equipment on Construction Electrical System
Yaping Wang · Mechanical & Electrical Engineering Technology · 2010
The quality of grounding equipment can relates directly to the security and normal operation of the construction electrical system.When we evaluate the performance of grounding grids,we mainly consider two parameters,grounding impedance and completion of electrical grounding.This article discusses tests and examples referring on the completion of grounding impedance and grounding grids.It also proposes unresolved problems to the accuracy of grounding resistance test and improving methods to the unqualified grounding in project.
