Information about cable and ambient temperatures in addition to pressure readings and system parameters are needed to calculate the cable fluid volume. While the cable temperature depends upon a number of fixed and variable parameters (including the changes in circuit load, which is already available in our Control System).
Obtaining real time pressure and temperature data from some fluid filled cable systems can be challenging due to their remote or extreme locations, which can include buried, in partially flooded roadway pits and exposed, on raised electricity tower platforms.
This project attempts to integrate available monitored information to calculate changes in the cable fluid volume in a cost effective manner.
