Evaluation of limestone dust suitability as a cable backfill material in acidic groundwater conditions.

Buried high voltage cables are backfilled with cement-bound or selected sands which have desirable thermal properties, but high carbon and economic costs. Crushed limestone dust is a potential replacement material, yet its longevity and performance in acidic groundwater are unknown.

Smart hammer asset health index methodology

Asset replacement strategies need to factor in current fleet health as well as anticipated changes in order to pace expenditure manageably. Wooden pole assets on overhead line networks present a particular challenge given the diversity of their operating environments and the ways in which they face material degradation. The Smart Hammer provides the telemetry for measuring pole condition without subjectivity, but interpreting the volume of data it produces necessitates an automated assessment. The purpose of AM-10 was to validate the experimental design of health index classifier tests, recommend performance improvements and propose the means to make the assessment transparent.
