MV ground fault analysis and global grounding systems

2004
In 1999 the Italian Standard CEI 11-1, based on the CENELEC HD 637 S1 Standard, introduced, with reference to MV distribution systems, the notion of "global grounding systems", i.e. large interconnected grounding systems, able to keep touch voltages below safety limits, through lowering the equivalent grounding resistance and making the ground surface ...

Ground-fault protection of unit-connected generators

Electrical Engineering, 1958
THE INCREASING SIZE of turbine-generators on large power supply systems means that a sudden loss of a unit tends to endanger the continuity of power supply over large areas. Because of this, some operating companies prefer to sound an alarm upon the detection of generator ground faults which in themselves do not cause immediate disability of the ...

A New Method of Ground Fault Protection

Transactions of the American Institute of Electrical Engineers, 1934
A new high-resistance ``thyrite'' and a new 3-element cold-cathode tube having unusual characteristics constitute the basic elements in a new high voltage relay combination for relaying or detecting ground faults on ungrounded systems. This scheme of protection, as described herein, is characterized by its reliability, simplicity, sensitivity, and low ...
