Abstract :
This paper concentrates on the effects of d.c. mains voltage level selection on earthing and protection of the low voltage direct current (LVDC) distribution systems. Among the low voltage range the possibilities are to go up to 1500 VDC in unipolar and ±750 VDC in bipolar LVDC system. Voltage level selection is one of the main tasks in LVDC system design process as it directly affects the electric safety, structure and life-cycle costs of the system. The main outcome of the paper is on presenting the essential design aspects from earthing system and protection setup perspective, by utilizing case examples.
