Fund. f. … reactive power defined by IEC 62053-24 is reactive
power of fundamental harmonic component. This type of reactive
power is also defined in IEEE 1459-2010 as fundamental reactive
power:
Rem: Method affects calculation of all units (voltage, current, active power,
apparent power etc.)!
UNCONNECTED INPUT ......... Settings for unconnected voltage input checking
Check .......................... Whether to check (ON) or not (OFF) the presence of voltage on
measured object
ENERGY MEASUREMENT ..... Settings of energy measurement
Unit .............................. Unit of energy: Ws or kWh
Method ......................... Way of summing energy: 4Quadrant, Algo 1 (Net Result), Algo 2
(Positive Aggregate), Algo 3 (Both Sum), Algo 4 (Anti-fraud)
Sense ........................... (only for Algo 1 – Algo 4) Parameters are Import / Export and define
the direction of energy measurement
Time base ............................... integration time of measurement, valid range is 1s – 100s
VECTOR DIAGRAM ................ Settings of vector diagram displaying
Zero axis ...................... Position of reference zero axis: Vertical or Horizontal
Reference .................... Reference unit: Voltage or Current
HARMONICS ............................ Harmonics related settings
Phase Scale ................ Phase scale with values 0-360 or 0-360/n … n= harmonic number; in
second case will be phase values in these ranges: 2
nd
harmonic 0-
180°, 3
rd
harmonic 0-120°, 4
th
harmonic 0-90° etc.
ADDITIONAL INFO ................. Settings of special measurement
Power of harm. ............ Calculation and display of Active Power of higher harmonics
(for 2
nd
– 40
th
harmonic) on the Load Values screen: ON (enabled) or
OFF (disabled). Sign of the number determines direction of energy
flow: positive means energy consumption, negative energy
delivering. If the sign of this quantity (Ph) is different than the sign of
Active power (P), it means that higher harmonics are in opposite
direction against the total power.
Curr. phase seq. ......... Display of Current Phase Sequence on the Load Values screen: ON
(enabled) or OFF (disabled)
Lead/Lag indic. ........... Enable of Indication of leading or leading in the row cosφ on Load
Values screen. Indication is presented as small red triangle at the
corners of each channel L1, L2, L3, while up is LAG, down is LEAD.
