Sentence examples for ground currents from inspiring English sources
As such, the grid and the PV panels are directly linked, so the leakage ground currents, created through the potential fluctuations between the grid and the PV array, have a direct path [44].
As a result, most of the ground currents above the frequency of 100 kHz are dissipated into the earth near the current injection point and the high frequency grounding impedance of long counterpoises is converged into that of short counterpoises.
A very strong flare from the sun caused compression of the earth's magnetic field and a subsequent surge in ground currents, overloading the power relays.
On September 1, 1859, a solar storm occurred so strong that aurorae were visible as far south as Cuba and Hawaii, and associated ground currents sparked fires in telegraph offices.
Recent work has identified five principal sources of residential magnetic fields: electric power transmission lines, electric power distribution lines, ground currents, home wiring, and home appliances.
Therefore, the ground current can be reduced.
Therefore, the suppression of ground current is a necessity for the transformerless PV inverter [3].
The ground current results in electromagnetic interference and safety issues [2].
It can achieve the ground current reduction by keeping the parasite capacitor voltage free of high frequency components.
Performance evaluation is carried out to verify the effectiveness of the proposed topology for the ground current suppression.
It should be noted that this paper mainly focused on the ground current reduction in single-phase PV systems.
