Pantograph-equipped locomotives should not run via a segment split when 1 facet is de-energized. The locomotive would turn into trapped, but as it passes the area break the pantograph briefly shorts the two catenary strains. If the other line is de-energized, this voltage transient may perhaps excursion source breakers.

Depot spots have a tendency to own only a single wire and therefore are often known as "simple tools" or "trolley wire". When overhead line devices were very first conceived, fantastic current collection was attainable only at small speeds, using just one wire. To permit bigger speeds, two additional varieties of apparatus ended up made:
For instance, If your CLI had two modes identified as interface and method, the person may make use of the command interface to enter the interface mode.
