2.3.3 Power Supply
Check that the site power supply is stable. The centralized AC power system consisting
of mains, UPS, and self-supplied diesel generator should be
z Easy to connect
z Safe to operate
z Flexible to dispatch
z Convenient to maintain
The low-voltage power supply should adopt the single-phase three-wire system. Table
2-4 lists the nominal voltage and frequency of the low-voltage AC power supply.
