Home / Namibian power system temperature measurement optical cable model
To estimate the temperatures of conductor and XLPE (cross-linked polyethylene) insulation of the submarine cable based on the ambient temperature and optical fiber temperature, the thermoelectric coupling field model of the 110 kV single-core submarine cable is established and. The status of an optic–electric composite high-voltage submarine cable (referred to as submarine cable) can be monitored based on optical fiber-distributed sensing technology, and at the same time, no additional sensor is needed in the monitoring system. It is known that in cases of failure the underground transmission cables overheat locally, they become a hot-spot, and it is extremely difficult to detect and locate the. This paper presents the design and analysis of Fiber Bragg Grating Sensor to measure and monitor the temperature change in powerlines for a particular range of temperature. Simulation was carried out on Optisystem to determine the peak reflectivity of the Bragg wavelength. Nowadays, the power cables are manufactured to fulfill the following condition – the highest allowable temperature of the cable during normal operation and the maximum allowable temperature at short circuit conditions cannot exceed the condition of the maximum allowable internal temperature.
