Measuring Efficiency and Loss

3.5

Measuring Efficiency and Loss

The instrument can calculate the efficiency η (%) and loss (W) using the active power values and
motor power values, and display them. For example, the instrument can calculate efficiency and
loss between input and output of various power converters (e.g., inverters, power conditioners) as
well as motors, and simultaneously calculate the overall efficiency.

Efficiency and loss equations

You can set four or fewer equations (

η

1

to

η

4

and

Loss1

to

Loss4

) for each of efficiency (η) and

loss (Loss).

Select the parameters of the input side

of the equation.

2

Select the parameters of the output

side of the equation.

Select the input-side measured power value

on the left and the output-side measured

power value on the right for each figure on

the screen. Up to six inputs and outputs can

be selected for each efficiency calculation

equation. Efficiency is calculated using the

sum of the six.

•

Motor power (Pm) measurement is selectable only for the motor analysis-equipped model. Configure

settings using the motor input settings screen to measure the motor power (Pm).

•

See “Configuring the motor input settings” (p. 84).

•

Calculations across wiring configurations with different power ranges are performed using data for the larger

of the two power ranges.

•

Calculations across wiring configurations with different synchronization sources are performed using the

most recent data at the time of calculation.

To moderate measured value fluctuation

•

Measured values may exhibit variations when loads fluctuates severely or transiently. In this

case, reduce the data refresh interval (to 200 ms) and also use the average function’s moving

average mode.

•

When either the input or output is DC, variation in measured efficiency values can be limited by

using the same synchronization source setting for the channel used for DC measurement as for

the AC side.
