Areas of usage



Storage of grid parameters for a time interval for (graphical) evaluation via PC-software included in

the delivery



Recording and evaluation of minimum and maximum values



Recording of voltage and power curves



Recording and evaluation of harmonics in the grid

Evaluation of status and control behaviour of the compensation system by



Investigation of the correlation between switching behaviour, cos

φ and remaining reactive power –

thus fault detection and optimization of the system settings



Evaluation of system dimensioning



Recording of switching operations and switching times of all steps: detection of wear-off of

switching devices



Review of target output of switched steps compared to the measured reactive power – detection of

defective steps possible



Recording of temperature in the compensation system, early detection of thermal problems

Evaluation software for PC (Windows-compatible) included in the delivery

The particular PC-software allows the comfortable evaluation of the measured data, assessment of

grid parameters.



Display of grid parameters, cos

φ, reactive power



Reactive power of grid and system – cos

φ



Reactive power of grid and system – step status



Comparative display of ACTUAL and TARGET cos

φ



Diagrams of switched reactive power of the system



Harmonics



Temperature curve of the system during measuring

interval



Number of switching operations and switching times of

all steps as bar diagram – detection of wear-off

Cautions and warnings

The acquired measurement results must be considered as values that should help the user to track errors or for

evaluating a compensation system. The final rating is incumbent on the user.

Important: Please note that the „General Safety Recommendations for Power Capacitors“ by ZVEI

(German Electrical and Electronic Manufacturers´ Association (ZVEI) have to be observed in addition

to the caution guidelines stated in the data sheet (Internet: www.epcos.com/pfc).
