There is such a thing as a three phase to earth fault, so maybe this is what you mean by a "balanced earth fault". I don't believe any earth or ground currents would flow in this case. A restricted earth fault is a typical phase to earth fault, where the zone of protection is restricted to a specific area, such as around a transformer. "Restricted" is referring to the protection method, not what is actually going on with the currents and voltages.
They mean the same thing, a current to ground/earth that shouldn't exist in the circuit.
Restricted earth fault protection is used to protect a specific zone, and should not trip for a fault outside of that zone (usually limited to a transformer, and possibly extending to lowside, highside, and tertiary breakers).
Earth leakage relays are instantaneous tripping relays where as earth fault relays have the option of time and ampere setting i.e. for a setted ampere the circuit breaker will be tripped off after the setted time (in second).
A neutral wire provides a return path for the hot lead while an earth or "ground" wire is provided as a safety function only that is not normally intended to carry current except for the purpose of operator protection.
A two core cable is used where an earth is not required. A three core cable is used where an earth is requred. Specialised three core cables are available for 3 phase and two-way switching applications.
what is the difference between earth amd mars besides that earth has life
balanced between atmosphere and earth
yes
Difference between what? See related question
The difference is that the earth has one and the moon doesn't.
Earth has life on it.
the difference is that the earth's theory is similar to that of a hypotheses , structure and compositional layer of the earth.
it is a 7 million temperature difference
one for earth's and neptunes, small
penis
One orbits the earth.
yes there is a difference because into the inferno is after burning earth
