CCAS process collects data from 10% of the spans on the circuit and grades each span using a four number system. The Grade relates the amount of zinc remaining on the steel core bundle to a corrosion reference model created for the conductor being tested.
The data that the instrument generates is transmitted to a CCAS program called “ Analysis ”. This program has four primary functions: Data Capture, Reference Model Building, Data Analysis and Batch Printing for Report presentation.
In the report presentation these grades will be used to illustrate the level of corrosion. A circuit that receives a Grade #4 is at the end of its service life ( ESL ).
