• Calculation of equivalent capacity P0 of harmonic generating equipment
"Equivalent capacity" is the capacity of a 6-pulse converter converted from the capacity of consumer's harmonic generating
equipment and is calculated by the following equation: If the sum of equivalent capacities is higher than the limit (Refer to
page 66), harmonics must be calculated with the following procedure:
P0 = ∑ (Ki  Pi) [kVA]
Ki: Conversion coefficient (Refer to
Pi: Rated capacity of harmonic generating equipment
i: Number indicating the conversion circuit type
• Calculation of outgoing harmonic current
Outgoing harmonic current = fundamental wave current (value converted from received power voltage)  operation ratio 
harmonic content
• Operation ratio: Operation ratio = actual load factor  operation time ratio during 30 minutes
• Harmonic content: Refer to
• Rated capacities and outgoing harmonic currents of inverter-driven motors
