Grid

Meaning in electrical & electronics engineering, with examples

/ɡrɪd/nounCore term

In electrical & electronics engineering, grid means: The interconnected network of power plants, transmission lines, substations and distribution lines that delivers electricity to consumers. It is also called the power grid or the mains.

In Turkish: şebeke, elektrik şebekesi, enterkonnekte sistem

How it is used

Used in energy, power engineering and renewables. Plants and solar farms are connected to the grid and feed power into it; homes draw power from it. Engineers talk about grid frequency, grid voltage, grid stability and grid connection; an off-grid system works without it.

Example sentences

  1. The wind farm will be connected to the grid through a 154 kV substation.

  2. When the grid fails, the UPS keeps the servers running until the generator starts.

Common collocations

  • power grid
  • grid connection
  • grid frequency
  • connect to the grid
  • off-grid
  • transmission lineA high-voltage line, usually overhead on towers, that carries large amounts of power over long distances. In electronics, the term also means a cable or trace whose impedance has to be controlled.
  • substationA facility in the power network where transformers step the voltage up or down, and where circuits are switched and protected with breakers, disconnectors and protection relays.
  • generatorA machine that converts mechanical energy, for example from an engine, a turbine or the wind, into electrical energy. A standby diesel generator supplies power when the grid fails.
  • frequencyThe number of times a signal repeats its cycle in one second, measured in hertz (Hz). Mains electricity in Turkey has a frequency of 50 Hz.
  • inverterA power electronic device that converts DC into AC. Inverters connect solar panels and batteries to the grid, supply AC loads in UPS systems and produce variable-frequency AC in motor drives.
