A motor starting may draw 6× FLC for 5–10 seconds. The demand interval (15 min) averages this out, so starting current rarely contributes to MD unless starts are frequent and long.
Maximum demand refers to the highest amount of electrical power consumed by a system over a specific period, usually measured in kilowatts (kW). For 3-phase systems, which are commonly used in industrial and commercial settings due to their efficiency and ability to handle higher loads, the calculation can be a bit more complex compared to single-phase systems. maximum demand calculation 3 phase
MD (kVA) = (170 kW / 0.8) / 0.9 ≈ 236.11 kVA A motor starting may draw 6× FLC for 5–10 seconds
Assuming a diversity factor of 0.8 and a power factor of 0.9: maximum demand calculation 3 phase
