Reliability
of Cables and Lines
A power transmission system
must reliably deliver power of a given quality
to all parts of the network. There are high economic
and social costs if this is not possible. For
example, grid outages may mean that commerce must
close down unpredictably, leading to missed deliveries,
lost batches or damage to equipment that cannot
take shutdowns - such as glass furnaces. To manage
unreliability, industries may need to maintain
their own standby sources of power, which are
costly and reduce competitiveness.
Performance standards ensure
that power transmission systems are very tightly
controlled. Choose from the topics below to learn
more about the N-1 criterion for system reliability
and how systems cope with failure.
