Power Factor Controller,

8 steps

For LV compensation

3 Phases , 3 Current Transformers

General Information
When traditional type reactive power controllers are used, especially for unbalanced3-phase systems, the compensation process gets more
complex and for some situations, it is a nightmare. To overcome this problem, experience, knowledge and scientific background
are put together with the help of high technology and VARko-3xx, 3 phase evaluative reactive power controller, is developed by KAEL
The most important properties of VARko-3xx 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 cosΦ value, compensate the system as much as close to the 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 on its own as it operates),
5- Dynamically adjusting normal region boundaries and capacitor switching on&off times concerning consumed reactive/active
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 the 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,
10- Compensation concerning resultant power factor(Σ cosΦ) calculated as the vectorial sum of three phase powers.
