How to Read and Understand an Electrical Single Line Diagram
End-users: Use the single-line diagrams to identify their electrical equipment, circuits, and protection apparatus. Familiarity: Familiarity with electrical symbols helps one to understand the overall system connections. Example of Single Line Diagram (SLD) The above single line diagram shows right from generation to distribution stage.
Electric power transmission - Wikipedia
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation interconnected lines which facilitate this movement are known as a transmission network is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution.
Signal Generator: What are They? Circuit & Block Diagram
Feb 24, 2012What is a Signal Generator? Signal generators are electronic devices that generate electronic signals and waveform. These electronic signals are either repeating or non-repeating as per the requirements and field of applications. There are different types of signal generators with different level of capability and functionality. All the signal generators

Automotive Relay Diagram! 4 & 5 Pin Relay Wiring Diagram
The coil circuit’s two wires are terminals 85 and 86, in which terminal 85 is considered negative contact and terminal 86 is considered positive contact. The five-pin relay’s high amperage circuit consists of three terminals 30, 87, and 87a. Terminal 30 is a common contact, the battery power comes through this terminal to the battery.

Open circuit test & Short circuit test in transformers
The impedance and other circuit parameters can be determined by conducting simple no-load tests. No-load tests have a minimal power loss when compared to that during direct load tests. The input voltage, current, and power are measured and based on that the equivalent circuit parameters can
Electrical engineering - Wikipedia
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism emerged as an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electrical power generation, distribution, and use.
