Glossary

ACSR Aluminum Conductor Steel Reinforced: A type of high voltage conductor cable with a core of one or more galvanized steel strands for mechanical strength surrounded by aluminum wire strands that carry the current.

CCAS Conductor Corrosion Assessment System: A process for testing high voltage ACSR transmission conductors to determine the amount of corrosion that has taken place. Testing can be performed on live lines or de-energized lines.

ESL End of Service Life: The point in time when the CCAS evaluation indicates that the conductor being tested is unreliable mechanically due to corrosion of the steel core and\or the aluminum strands.

LLW Live Line Working: Maintenance or testing being performed on a line while it is energized.

OLW Off Line Working: Maintenance or testing on a de-energized line without voltage.

RSL Remaining Service Life: The estimated time remaining before the circuit reaches the ESL.

STC Shannon Technology Corporation: A provider of CCAS services to the Electric Power industry in the United States for the evaluation of ACSR. STC provides a condition assessment and projected RSL for aging conductors.

SDC Shannon Developments Corporation: A provider of CCAS services to the Electric Power industry outside the US for the evaluation of ACSR. SDC provides a condition assessment and a projected RSL for aging conductors.

Control et Maintenance: CCAS representative in France.
