Protective devices - relays, CT,PT, isolators, circuit breakers are used for fault protection. Fault protection means If there is a fault in the circuit, the circuit must be cut off before any damage occurs due to fault.
If the earth connection has a high resistance it is not capable of acting as a true earth. For example, the high resistance might mean that the fuse or circuit-breaker will fail to operate when there is a fault.
The item for which the LED indicates is in a fault condition. Since there exist many brands of PLCs, there are many conditions indicated such as BUS FAULT, SYSTEM FAULT, I/O FAULT, COMMUNICATION FAULT, and many others.

what do you mean by 50 KA for 1 sec
elecric drives are basically big electric motors which are used to drive generators
An electric circuit grounding.
'Overcurrent protection devices' are used to protect conductors from excessive current flow... a fuse
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.
Original Answer (Physics): Gravitational Potential Energy -------------------- Electrical Answer: If this is electrically related, perhaps you mean GFPE which means Ground Fault Protection for Equipment.
what is mean by deplomatic relation
Trailer Brake Control fault.
Means that the onboard computer in your car thinks there's something wrong with your airbag(s). If you want full protection in case of a collision, have a mechanic check it out.
Fault. Mea culpa--my fault. Culprit--the person at fault.
To foster a relation means to grow the relation.
In a symmetric distribution, the mean and the median are the same. Otherwise there is no relation. In symmetric distributions with only one mode, the mode will coincide with the mean and median, but otherwise there is no relation.
