Crimping is joining two or more pieces of metal or other ductile material by deforming one or both of them to hold the other.

Creep (sometimes called cold flow) is the tendency of a solid material to move slowly or deform permanently under the influence of persistent mechanical stresses.

A crankshaft is a shaft driven by a crank mechanism, consisting of a series of cranks and crankpins to which the connecting rods of an engine is attached.

A crank is an arm attached at a right angle to a rotating shaft by which circular motion is imparted to or received from the shaft.

A crane vessel, crane ship or floating crane is a ship with a crane specialized in lifting heavy loads.

An electrical grid is an interconnected network for electricity delivery from producers to consumers.

In an electric power system, a fault or fault current is any abnormal electric current.

Electrical energy is energy derived as a result of movement of electrons, energy that has been converted from electric potential energy.

The efficiency of a system in electronics and electrical engineering is defined as useful power output divided by the total electrical power consumed.

An electrical contact is an electrical circuit component found in electrical switches, relays, connectors and circuit breakers. Each contact is a piece of electrically conductive material, typically metal.

An electrical connector is an electromechanical device used to join electrical conductors and create an electrical circuit.

An electrical conduit is a tube used to protect and route electrical wiring in a building or structure.

Electrical conductance is the ease with which an electric current passes.

An electrical circuit is a network consisting of a closed loop, giving a return path for the current.

An electrical cable is an assembly of one or more wires running side by side or bundled, which is used to carry electric current.

Braking of a small wind turbine can be done by dumping energy from the generator into a resistor bank, converting the kinetic energy of the turbine rotation into heat.

A fault where all the conductors are considered connected to ground as if by a metallic conductor. In one type of transmission line protection, a "bolted fault" is deliberately introduced to speed up operation of protective devices.

A short circuit between lines, caused by ionization of air, or when lines come into physical contact, for example due to a broken insulator.

A short circuit between one line and ground, very often caused by physical contact, for example due to lightning or other storm damage.

A short circuit when two lines come into contact with the ground (and each other) commonly due to storm damage.
