Question #: 16
Topic #: 2
A high kW demand on a facility electrical consumption report is noted for a one-hour interval. Consumption is less than normal for the same interval. Which of the following could be the cause?
A demand spike (kW) can occur when multiple large motors or systems restart simultaneously after a power interruption. Although energy consumption (kWh) over the interval may be less, the instantaneous demand registers higher because of inrush currents during restart. This aligns with CHFM exam energy management principles.
