Surge impedance loading aware reactive power management system for offshore oil and gas facilities
Results in EngineeringLong HVAC submarine cables inject substantial charging MVARs. They cause the Ferranti effect at the receiving end and also shrink the cable’s ampacity margin. This paper presents a Surge Impedance Loading Aware Reactive Power Management System (SILARPMS)

Ampacity test of 28 AWG ribbon cables [PDF]
, 1990 This report contains the results of testing ribbon cables in order to determine the amount of current they can carry. In some experiments ribbon cables are used to power circuit boards and carry several amperes of current. These tests were required to establish safe operating current limits for electrical safety reviews.
