Background:
The Activcomp is a state of the art, electronic switching system designed for power factor correction and Harmonic filtration.

Connection and disconnection of the capacitors to and from the network occurs at zero current crossing. This smooth connection avoids the transient effects typically created by electro mechanically switched PFC systems.

The electronic switches do not wear out or deteriorate during the switching process and the capacitors are not adversely affected by transients. These advantages contribute to a much longer life expectancy compared with electro mechanically switched PFC systems.

The power factor is controlled very accurately by means of an advanced closed loop control and measuring unit, that takes into consideration all three phases and the effect of harmonics (1 through 63).

The Activcomp system is equipped with a unique scan feature that protects capacitors from "exploding" and contributes to longer life expectancy. This is achieved by reducing over current and overheating in the capacitors which may result from harmonics on the mains. The switching element can perform an unlimited number of switching operations. The connection of one group of capacitors occurs simultaneously with the disconnection of another group. This operation is performed every few seconds and engages all capacitor group in turn, resulting in a reduction of mean current due to the lower ratio of engagement time to cycle time (duty cycle).

The scan feature, together with the unique reactor design, substantially reduces the temperature rise of the reactors and protects the cabinet from overheating.

Advantages Over Electra-mechanical Compensation System:

Fast and Accurate Compensation:
The Activcomp is a Transient Free Fast Compensation System. It is used for Power Factor Correction & Harmonic Filtration. The compensation is based on averaging the FFT analysis of each cycle, resulting In more accurate compensation, even in the presence of harmonics.

Simultaneous Group Connection:
When load changes require connection or disconnection of more than one step, the Activcomp controls the switching of as many steps as required at precisely the same time. Simultaneous connection or disconnection provides the following benefits:

Fastfull compensation.
For Eg., with 1:2:2 system configuration and groups 1 & 2 are connected. When 1 more step is required, group 3 will be connected simultaneously while group 1 is disconnected.
Real binary sizing - 1:2:2 is exactly the same as 1:1:1:1:1.

Transient-free Switching:
Electronic switching technology prevents any transients typically associated with conventional capacitor switching. This is extremely important in sites with sensitive electronic equipment, such as hospitals, data centers and facilities.

Fixed Capacity & Filter Characteristics:
The capacity of the Activcomp capacitors is virtually permanent over the years, which prevents the need to replace capacitors. Moreover the tuning frequency remains constant over time, which allows system performance to remain atthe highest possible level.

There is an ongoing cumulative reduction of capacity in electro mechanically switched PFC systems due tothe effect of transients during connections and disconnection. This can be detrimental to detuned electro mechanically switched systems where the changes in ratio between the capacitors/reactors shift the resonance frequency, which may result in resonance. The Activcom p prevents these conditions.

Capacitor Duty Cycle-SCAN ModeL:
The unique SCAN feature protects the Activcomp's capacitors & reactors, increases their lifespan. Simultaneous connection and disconnection of steps in FIFO (First In First Out) manner is shown in diagram on the previous page.
