South African Institute of Electrical engineers validated course re ‘HV/MV Circuit Breaker Maintenance, Safe Operation & Theory’ course. The students might need more info on the newer Insulating Technologies now available. Siemens for example are looking at replacing SF6 with a gas consisting of 80% nitrogen + 20% oxygen; ABB are experimenting with CO²gas.Well the CB’s we cover are up to date with the latest available besides the above-mentioned new design which will only be available later. At the moment SF6 and vacuum insulated gear is very prevalent in the electrical industry. This includes GIS and Hybrid CB’s.
As you probably know, there are basically three fields in the HV/MV Electrical Power System Grid. Circuit Breakers, Power Transformers and Protection, Test & Commissioning. These are the main issues when looking at a power grid system, whether its Distribution, Transmission or Generation. We cover the HV/MV Circuit Breaker field.
