AC Linear Resistance
With the soaring needs for electric power transportation capacities, the conductor cross-sections of power lines have not ceased to increase over the last decades. This greatly impacts the sensitivity of the cable linear resistance to the skin effect present in alternative current (AC) conditions. As a consequence, measurement of the AC Linear Resistance of conductors is required to properly qualify large cross-section conductors
Measurement of the AC linear resistance of conductors is required to properly qualify large cross-section conductors, as DC linear resistance measurement can not take into account the skin effect at frequencies of 50 and 60 Hz for such cross-sections.
AESA has developped an apparatus for its Testing Laboratory to measure this AC Linear Resistance. The apparatus follows the Technical Brochure of CIGRE about recommendations on AC measurement techniques.
Up to now, no standardised experimental method for measurement of AC linear resistance of conductors has been defined and a CIGRE working group is presently preparing recommendations to carry that type of measurement. For information, this CIGRE working group is being chaired by AESA.
The CIGRE TB272 technical brochure indicates some approaches of AC measurement.
