BSPT
BSPT: British Standard Pipe is a family of technical standards for screw threads that has been adopted internationally for interconnecting and sealing pipes and fittings by mating an external thread with an internal thread.

Busbar
An electrical conductor that makes a common connection between several circuits. Sometimes, electrical wire cannot accommodate high-current applications, and electricity must be conducted using a more substantial busbar — a thick bar of solid metal (usually copper or aluminium). Busbars are uninsulated, but are physically supported by insulators. They are used in electrical substations to connect incoming and outgoing transmission lines and transformers; in a power plant to connect the generator and the main transformers; in industry, to feed large amounts of electricity to equipment used in the aluminium smelting process, for example, or to distribute electricity in large buildings

Capacitance
Capacitance: A measure of the amount of electric charge stored (or separated) for a given electric potential. The most common form of the charge storage device is a two-plate capacitor.

Capacitor
(also referred to as a condenser) A multi-purpose device that can store electrical charge in the form of an electric field. It is used, for example, for power factor correction in (inductive) AC circuits. Capacitors are used to buffer electricity (smooth out peaks) and to guard against momentary voltage losses in circuits (when changing batteries, for example).

Carbon cycle
The circulation of carbon through its various forms in the environment. Briefly, carbon dioxide in the atmosphere is fixed (i.e., converted into solid matter) by the process of photosynthesis in plants and green algae. These then die and rot under the influence of bacteria and fungi or are consumed by higher organisms in the form of food or fuel (burning plant matter or fossil fuels). Either way, carbon is released into the atmosphere as carbon dioxide and is available again for fixation (i.e., incorporation into biomass).

Cascading power failure
A cascade happens when a part of the power grid fails and shifts its power load to other elements in the grid. Overloaded, these elements also begin to shut down and shift their power load onto other elements, and so on. The resulting surge current can induce ongoing failures and take down an entire power system in a very short time, “cascading” through parts and systems like a ripple on a pond until the grid collapses

Charging station
An installation at which an electric vehicle can be plugged into the grid to charge its battery. There are several types of charging station, including low-voltage, lower current installations that charge a battery over a period of several hours (for use in homes, for example), and higher-voltage, higher current fast-charging stations for a more rapid service in public places (car parks, public buildings, etc.).

Circuit breaker
Devices that interrupt high currents to protect electrical equipment from damage caused by current surges, e.g., from a short circuit or a lightning strike.

Co-generation
A particularly efficient method of electricity generation that diverts heat, produced as a by-product of the power generation process, to domestic and industrial heating systems. The heat is produced by combustion of fuel in the power station to create the steam that drives the generating turbines. It would otherwise be released to the atmosphere.
