Risk Equals Probability Times Consequences | TD World

Failure RatesTypical Transformer Fire ScenariosOil-Impregnated Bushing FiresCable Termination FailuresTank RupturesInternal Arcing and Tank RupturesMitigation of Transformer Fire RiskProtection of Substation AssetsStandard PrecautionsContingency PlanningThe failure rate varies considerably between transformer users. It depends on the quality of the design and manufacture, the procurement policy, and the operation and maintenance practices. The type of transformer also is a factor, as failure rates tend to be above average for auto-transformers and generator step-up transformers, and below average for the two winding transformers installed on transmission and subtransmission systems in the 11-kV to 300-kV voltage range. Statistics confirm the failure rates increase on transformers with operating voltages above 300 kV, and the consequences of a failure fire is more severe on systems with high fault levels. Data on the probability of a transformer fire is limited, but much more information is published on the probabilities of transformer failures. The probability of a transformer failure varies considerably among utilities and types of transformers, but the probability of serious failures is typically in the range of 0.5% to 2.5% per...Get price

Electrical substation - Wikipedia

A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two diGet price
