8-3 Electrical measurements in the Main Circuit

The indicated values depend on the meter types because of harmonic components included in the voltage and current of the main power supply (input) and the output (motor) side of the drive. Therefore, when measuring with a meter for the commercial power frequency, use the meters shown in Table 8-3-1.

The power-factor cannot be measured using the power-factor meter available on the market which measures the phase difference between voltage and current. When the power-factor must be measured, measure the power, voltage, and current on the input side and output side. Then, calc ulate the power-factor using the following formu- las:

Three-phase

	Power factor =	Electric power [W]	x 100 [%]
	Power factor =	3 x Voltage [V] x Current [A]	x 100 [%]
		3 x Voltage [V] x Current [A]
	Single -phase
	Power factor =	Electric power [W]	x 100 [%]
	Power factor =		x 100 [%]

Voltage [V] x Current [A]
