Heating phenomenon in high-voltage system busbars
The flow of current through the busbar generates heat due to resistive losses, a phenomenon known as Joule heating. Joule heating is characterized by the conservation laws governing electric current and energy. The thermal analysis takes into account the heat conduction and convection of a copper busbar system used to supply a test bench with high currents in order to check the electro-thermal behaviour of power circuit breakers during overload and short circuit conditions. Typically devoid of insulation, these busbars possess the necessary rigidity to be supported in the air by. While air cooling affects both battery cells and busbars, liquid cooling offers superior thermal performance but primarily targets battery cells, making it less effective for managing heat in busbars. Under high-current conditions, busbars can generate significant Joule heating, increasing local. In the present paper, based on the finite element method, the heat transfer in the busbar room of KYN28A high voltage switchgear is numerically studied using the electromagnetic-heat-flow coupling model.

Basic Structure of Optical Circulators
An optical circulator is a three- or four-port designed such that entering any port exits from the next. This means that if light enters port 1 it is emitted from port 2, but if some of the emitted light is reflected back to the circulator, it does not come out of port 1 but instead exits from port 3. This is analogous to the operation of an electronic. Fiber-optic circulators are used to separate optical signals.
