Summary:Resilience of power supply grid can be increased substantially by more accurate pole inspection and testing. Electric utilities are unnecessarily replacing or re-enforcing electrical poles that still have many years of useful life. Our proof load testing of rejected poles has revealed that around 50% of them had residual strength sufficient for around 20 additional years of serviceable life. The present assessment of poles is very subjective. Poles are often replaced simply on the basis of their age rather than condition. Independent destructive testing of poles has found that the present pole inspection methods reject 60% of safe poles and miss 20% of unsafe poles. According to our statistics, based on the recent results of using our Micro-Stress Pole Testing (MSPT) technology, the expected savings on electricity cost can be approximately 100 billion dollars per annum if all poles around the world are objectively and precisely tested. The above cost savings can be used for substantial increase of resilience of power supply grids (for example, for insulation of wires against the fire hazard, elimination of hidden dangerous poles etc).
