Can be stored in batteries to be used anywhere and anytime.
Is abbreviated as AC in English and CA in Spanish.
The transport via cable has few losses thanks to the high voltage.
Circulates from positive to negative pole of generator.
A single electrical signal returns by the cable called NEUTRAL, that closes the circuit.
Colours: blue for NEUTRAL and black, brown or grey for PHASE.
Periodically changes intensity and direction.
Abbreviated as DC in english and CC in spanish.
The distribution network is cheaper because the conductive cables are thinner.
Its transport via cable is subject to very high losses.
230 V between PHASES and NEUTRAL and 380 V between two different PHASES.
Produced in batteries and dynamos.
A single electrical signal is transmitted by the cable called PHASE.
It is the AC that arrives to our homes.
The frequency is also 50 Hz.
PHASE conductor contains 3 cables differentiated by colours: black, brown and grey.
It is a system of three connected AC currents, produced simultaneously in the same generator.
Is produced in electrical power stations.
AC generators are easier to make, cheaper and need less maintenance.
Constant intensity and direction.
In Spain, uses a voltage of 230 V and a frequency of 50 Hz.
Can be easily turned into DC.
Has a single NEUTRAL returns cable wich colour is blue.
