“…In both experiments, the measured temperature gradually increases as the duration of the experiment increases. Figure 23 distinguishes the measurement of the temperature rise on bottom isolating contact based on the IEC standard and the innovative method [18]. Based on the plotted chart, it relatively describes the linear relationship of the temperature rise between IEC standard and the innovative method on the bottom of isolating contacts.…”

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.

If an R.M.U. (Ring Main Unit) cubicle is installed, operated and maintained in accordance with current standards and the manufacturer’s instructions, the likelihood of internal arcing is reduced, but should not be completely ignored. This article outlines the experimental situations in which arcing can occur and the catastrophic effects seen if R.M.U. is not properly designed for this type of damage. This type of failure can be caused by a fault, abnormal operating conditions or a malfunction and represents a danger during its installation and to persons present. The situations in which this type of failure can occur are presented and experimentally analysed: bi-phase internal arcing in the connections compartment, three-phase internal arcing in the switching compartment, internal arcing in the fuse compartment and single-phase arcing between a phase and the switchgear enclosure.
