The grounding resistance measurement of distribution boxes plays a vital role in protecting staff and improving power supply quality.Aiming at addressing inaccurate measurement and potential safety hazards in the measurement process and inspired by the TRIZ theory,this paper analyzes the distribution box grounding resistance measurement,i-dentifies the conflict problem,then proposes the use of conflict matrix and invention principle for solution.Furthermore,a variety of design schemes and an actually practical case of distribution box grounding resistance measurement system are put forward,which facilitate accuracy and security improvement.
