3.12.2 Description of operation function
Efficiency
Definition: The active power P2 measured by Unit 2 is taken as the active power input on the primary side of the converter,
and the active powers P1 and P3 measured by Units 1 and 3 are taken as the power consumed on the secondary side of
the converter to calculate the efficiency.
Efficiency formula: Efficiency = (P1+P3) /P2*100%
⚠ CAUTION
If the denominator in the formula is less than or equal to 0.0001% of the rated range, the efficiency is displayed as
"ERROR".
Peak factor
Symbols: CF U1, CF U2, CF U3, CF I1, CF I2, CF I3.
Definition: Represent the ratio operation results of peak value and RMSof signals U1/U2/U3/I1/I2/I3, respectively.
⚠ CAUTION
When the RMS falls to 0.5% or less (peak factor 6 falls to 1% or less), the peak factor will be displayed as "Error" (see
Section 9.7 of this book for details). The peak factor can be calculated even if the measurement mode is MEAN or DC.
Arithmetic operation
Symbol expression: A+B, A-B, A*B, A/B, A
２
/B, A/B
２
The values of Display Bar A and Display Bar B are taken as operation items, with the operation results displayed in Display
Bar C. During operation, Display Bar C only displays the numerical value and the quantity level of units, and the data in
Display Bar A and Display Bar B need to be operated according to units. If the operation formula is set to A+B, 100mA is
displayed in Display Bar A, and 1V is displayed in Display Bar B, the operation result in Display Bar C is 1.1.
⚠ CAUTION
When the function displayed in Display Bar A is integral elapsed time (TIME), the calculation result will be displayed as "--
--", with no data. When dividing, the operation value is displayed as "Error" if the value of the display function in Display
Bar B is equal to 0 or no data is displayed,.
Integral average active power
Symbols: AV P1/ AV P2/ AV P3/ AV P4
Definition: AV P1: Display the result of the division of watt-hour (WP1) of Unit 1 by the integral time.
AV P2: display the result of the division of watt-hour (WP2) of unit 2 and integral time.
AV P3: display the result of the division of watt-hour (WP3) of unit 3 and integral time.
AV P4: display the result of the division of watt-hour (WPΣ) of unit Σ and integral time.
⚠ CAUTION
The value of watt-hour WPΣ depends on the wiring mode. This operation function is only useful during integral period
(integral operation or integral pause). If the integral is reset, the values of watt-hour and integral time will become zero,
and the result shows "------" without any data.
