A switching station is a substation without transformers and operating only at a single voltage level. Switching stations are sometimes used as collector and distribution stations. Sometimes they are used for switching the current to back-up lines or for parallelizing circuits in case of failure.
The term switching station may refer to: an electrical substation, with only one voltage level, whose only function are switching actions. a battery switch station, such as the ones used by the Better Place network. a railroad switching station. a telephone switching station
A substation is “a high-voltage electric system facility,” OSHA says, where power — specifically, voltages — becomes suitable for distribution and supply to customers.
High-voltage switching can be used to handle more cases, e.g., working transformer but faulty feeder or the reverse. Network protectors , (reverse current relays), are used to detect any open circuits that are letting the electrical current flow back towards its source.
Substation near Yellowknife, in the Northwest Territories, Canada. Distribution networks are divided into two types, radial or network. [10] A radial system is arranged like a tree where each customer has one source of supply. A network system has multiple sources of supply operating in parallel. Spot networks are used for concentrated loads.

The traction current supply lines from the nuclear power station Neckarwestheim to the traction current switching station at Neckarwestheim and from there to the central substation in Stuttgart, Zazenhausen are implemented as a four-bundle conductor circuit.
Welsh HVDC Converter Station is an HVDC back-to-back station connected between the J. Robert Welsh Power Plant and the Oncor Electric Delivery substation at the Monticello Steam Electric Station in Titus County, northeastern Texas. It went in service in 1995 and it can transfer a maximum power of 600 megawatts.
