“…Nonetheless, having simpler methods for predicting and verifying the temperature rise of the switching device is advantageous. The difference between the temperature of an element or part measured and the ambient air temperature outside a switchgear assembly is known as temperature rise [4][5][6]. The observed temperature difference between the main circuit and the temporary test connections at a distance of 1 m should not exceed 5 • C, according to IEC standard 62271-1 High-voltage switchgear and control gear-Part 1: Common specifications, paragraph 6.5.2.…”

“…It is advantageous to have simpler ways for predicting and verifying switchgear temperature rise. When dealing with the early stages of switchgear design, such a strategy could be useful [4][5][6][7]. The research on the temperature distribution in the switchgear is crucial for the optimum design consideration and maximizing the service life of the switchgear [1][2][3][4].…”

“…Different approaches are available for thermal stimulation in terms of modelling complexity. The researchers use additional available computer software such as the Finite Element Method, COMSOL Multiphysics, Computational Fluid Dynamic solver, ANSYS etc [1,4].The simulation required the accurate calculation of mathematical and numerical models to obtain the switchgear's temperature distribution [8]. Although this technique is widely applied, researchers experienced the difference between computer simulation value and actual experimental setup [9].…”

Modern civilization is characterised by a high need for electrical energy. The importance of electricity in daily life has grown to the point that it is desirable to safeguard the power system from damage during fault situations and to ensure maximum supply continuity, which necessitates the use of switchgear. Testing of any electrical equipment indicates the extent to which the equipment is able to comply with a customer's requirements. In this paper temperature rise test on a medium voltage switchgear assembly is considered. In this research, sub-clause 6.5.2 of IEC standard 62271-1 is followed to conduct temperature rise test on a medium voltage switchgear assembly. The test is conducted on two modes, first following the existing method of testing and second by an innovative method of testing. The temperature rise test is conducted on a 12 kV, 50 kA, 3150 A single busbar switchgear assembly and the readings are measured, analysed and compared between the two methods. It is concluded that the temperature rise recorded following the innovative method is more accurate compared to the existing method, as an increase in the recorded temperature rise is seen in all the thermocouple locations as the heat dissipation to the ambient is reduced.
