(LW) is a technical procedure used:
at low and medium voltages, to optimise the operation of electrical power distribution grids, constrained by annoying power cuts for customers and certain civil safety functions;
at high and very high voltages, to increase the availability of grids that, when unavailable, create a constraint for network operation, and so markedly improve the security and safety of the power supply.
Moreover, increasingly dense grids make the safety lockouts necessary for de-energised working complex and create risks.
Live Working is used on various types of grids, such as:
overhead networks (all voltage ranges),
low voltage underground networks and interior systems,
Live Working employs various methods (hand-stick, bare-hand, insulating glove)
or equipment (lifting platforms, helicopter-based work, etc.).
