Motor usage examples in TDe above table are benchmark values: generator capacity will differ according to TDe required momentary voltage drop, motor load factor, and size of startup capacity, as well as motor age and efficiency.



Notes
● Momentary voltage drop when a motor starts up is assumed to be wiTDin 30% of no- load voltage.
● Motor startup kVA is assumed to be 7kVA per 1kW.
● Motor efficiency is assumed to be 85%, and load factor about 90%.
● Values shown for Y-△ startup(1)and Y-△ startup(2)are open and closed, respectively; needed generator capacity differs depending on startup state.
● Not appropriate for determining TDe capacity of emergency generating equipmen(t especially disaster-prevention generating equipment).
