General Informations
When traditional type reactive power controllers are used, specially for unbalanced 3 phase systems, compensation process gets more
complex and for some of the situations it is a nightmare. To overcome this problem, experience, knowledge and scientific background
are put together with the help of high technology and VARkombi-PC, 3 phase evaluative reactive power controller, is developed by
KAEL Elektronik.
The most important properties of VARkombi-PC that make it different from traditional type controllers are;
1- Measuring current and voltage samples from all 3 phases, calculating active and reactive powers and storing consumed energies,
2- Instead of reaching to target tanΦ value, compensating the system as much as close to real axis between the capacitive and
inductive bound values. (Bound values can be changed by the user when desired),
3- Automatic C/k calculation,
4- Automatic learning and monitoring of capacitor bank powers (capacitor bank powers can be set by the user when desired. Device
also detects any false setting and corrects it by its own as it operates),
5- Dynamically adjusting of normal region boundaries and capacitor switching on&off times with respect to consumed reactive/active
percentage,
6- Extending capacitor bank power life by storing switching on&off times separately for each bank,
7- Automatic learning of current transformer polarities even if (k,l) is connected in reverse direction,
8- Calculating current reactive power value and directly switching on or off the most suitable group instead of sequential switching,
9- Making system tracking and fault detection easier with many hand alarms,
