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).
ELCB means Earth Leakage Circuit Breaker -- it is used to trip the Circuit breaker if any leakage fault occured means
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.
ELDB stands for Earth Leakage Detection and Breaker. It is a device used in electrical systems to detect any leakage of current to the earth, which could be potentially dangerous. When a leakage is detected, the ELDB will trip the circuit breaker to cut off the power supply and prevent any electrical accidents. This is especially important in ensuring the safety of individuals and protecting electrical equipment from damage.
leakage resistance of a resister is type of fault which occurs at a specific voltage across the resister which are undertesting.
earth fault relay is also a type of over current relay but the set value of current or relay sensing current is much less than the maximum load current.in over current relay relay sensing current ise than maximum load current mor
a fault is a large crack in the earth. a fold is when the ground gets bent.
earth fault relay is similar like earth leakage ralay,but the 2nd one is more sensitiv.

A crack in the Earth's crust is a fracture where rocks have pulled apart, whereas a fault is a fracture where there has been movement along the fracture plane. In other words, a fault is a type of crack in the Earth's crust that has undergone displacement.
appropriate resistance is to be inserted between the neutral point of the transformer and the earthing mat to restricted earth fault current. for this purpose a sensitive earth leakage relay is used. in the event of a fault, fault current returning to the system neutral trips an earth leakage relay and disconnects the supply. anand r. ambekar

In North America they are known as a GFCI. Ground Fault Circuit Interrupter breaker.

Earth leakage circuit breakers can trip in the off position if there is a fault in the wiring or if the breaker itself is faulty. It could be due to high levels of leakage current or a short circuit. It is a safety feature to prevent electrical hazards and should be investigated by a qualified electrician.
