Opis:
In the last years the failure frequency of transformers increased, e.g. due to ageing or external hazards. In particular fires and explosions of main oil-filled transformers are considered as critical. Therefore, international experiences of transformer failures at nuclear and non-nuclear power plants and at substations have been investigated in more detail. Consequences of transformer failures with respect to a reliable electricity transmission and distribution as well as measures to enhance the reliability of critical infrastructure and to avoid blackouts are addressed.

Opis:
In recent years the failure frequency of transformers increased. In particular fires and explosions of main oilfilled transformers are considered as critical. Therefore, international experiences of transformer failures at nuclear and non-nuclear power plants and at substations have been investigated in more detail. Consequences of transformer failures with respect to a reliable electric power supply and distribution are addressed and proactive measures to enhance the reliability of critical infrastructure and to avoid blackouts are described.

Opis:
Studies on energy security can be found in many academic publications and in government and think-tank reports. Main goal of this article is to present the energy system in the Republic of South Africa, to discuss the phenomenon of load shedding and it indication of proposed changes required to existing solutions. Authors based their research on available literature newspapers articles, direct observation and the interviews with the residents of Johannesburg. South African’s economy is the second largest in Africa, just behind Nigeria. It accounts for 24% of continent’s GDP. It is ranked as an upper-middle income economy by the World Bank. The major producer and distributor of electricity in RSA is Eskom, which provides over 95% of the country’s energy usage. Load-shedding, also referred to as rolling blackout, is an intentionally electrical power shutdown. In South Africa it affect entire country.
