a cable or conductor used to carry electrical signals, optical signals, or electric power
a network of high-voltage cables and equipment that delivers electricity across a large region
a facility that transforms voltage levels and regulates electrical currents, typically situated in an electrical power distribution system
substație, stație de transformare
Energia generată la centrala hidroelectrică este transmisă în zonele urbane printr-o substație.
a protective device that automatically interrupts the flow of electricity in an electrical circuit when it detects an overload, short circuit, or other electrical fault, thereby preventing damage to the circuit and reducing the risk of electrical hazards
întrerupător automat, siguranță
(electrical engineering) a collection of devices like switches and circuit breakers that control and protect electrical equipment
a solid strip or bar of conductive material that distributes electricity to multiple connected circuits
(electrical engineering) using three alternating currents of the same voltage, each offset by one-third of a cycle
