Earthing Systems
In electricity terms, earthing is connecting a conductive element to the
ground via a conductive path.

Protective Earthing
Protective earhing (RA) is earthing of metal parts -that do not carry
voltage under normal operation but may carry voltage due to a fault- in
order to protect people or other living things against hazardous touch or
step voltage.
In a low resistance protective earthing, a fault voltage is fed through the
faulty circuit during the fault, therefore enabling the breakers to
instantly break the circuit and therefore cut the energy on the faulty
circuit.

Operational and Functional Earthing
Operational Earthing (RB) is the earthing of the voltage of active parts of
operational devices of an electrical facility that are under voltage
against earth in attempt to keep at a specific value (e.g. star point
earthing)
Functional Earthing (RF) is earthing of a communication facility or an
operational device in order to resume the desired function.
