| | Electrical network - Wikipedia, the free encyclopedia |
 | | An electrical network is an interconnection of electrical elements such as resistors, inductors, capacitors, diodes, switches and transistors. | | | The goal when designing electrical networks for signal processing is to apply a predefined operation on potential differences (measured in volts) or currents (measured in amperes). | | | To design any electrical circuits, electrical engineers need to be able to predict the voltages and currents in the circuit. |

| | PB Network Issue 53 Migrating Electrical Power Network SCADA Systems to TCP/IP and Ethernet Networking |
| | Electricity utilities are encouraged to test the performance of their detailed design proposals to verify the QoS configuration can deliver the required performance characteristics and that they have full confidence in the concept before it is implemented network wide. | | | Electricity utilities may wish to develop TCP/IP networking capability, such as the one shown in Figure 1, to support their power system operation and administrative functions. | | | Electrical protection systems have critical requirements regarding reliability and performance of communication links, so we do not recommend transfer of teleprotection signalling to TCP/IP networks until such time that connectionless networks have matured and can guarantee the required service for electrical protection systems at all times. |

| | In a linear network with multiple voltage sources, the current in any branch is the sum of the currents which would flow in that branch due to each voltage source acting alone with all other voltage sources replaced by their internal impedances. | | | Any linear voltage network which may be viewed from two terminals can be replaced by a voltage-source equivalent circuit comprising a single voltage source E and a single series impedance Z. | | | The voltage E is the open-circuit voltage between the two terminals and the impedance Z is the impedance of the network viewed from the terminals with all voltage sources replaced by their internal impedances. |

| | InformationWeek Powerline Networking Langa Letter: Powerline Networking Comes Of Age January 13, 2003 |
| | First and foremost, like wireless networking (a form of radio), a powerline network requires no new cables or special wiring: Any building that has normal electrical service already is wired for powerline networking, with no need to snake cables through walls or under floors, and with no need for drilling or other structural work. | | | In this way, an electrical system can simultaneously deliver power and data over the same wires: Powerline networking devices can see and decode the networking signals, but standard electrical devices -- lights, motors, etc. -- don't even know the network data signals are there, and continue to operate normally. | | | Second, and again like wireless networking, powerline networking spreads the signal around: Once the network signal is injected at any point into a wiring system, the network can be accessed from almost anywhere on the same electrical system. |

| | The new optical network only performs cross-connecting of multigigabit streams, whereas the electrical network is responsible for cross-connecting low to medium bit rate streams and generating the multigigabit streams. | | | It should be noted that even in a transparent network there are restrictions on the physical parameters of the signal offered by the source (i.e., input power, optical frequency, or bandwidth cannot be arbitrary). | | | The generic approach used there is independent of the network technology and is based on a layered concept with a client/server relation between adjacent layers. |
