Activcomp System

Conventional Automatic Power Factor Correction Systems (APFC) which were commonly installed in majority of installations to improve power factor till few years back. These systems are having severe limitations in installations with dynamic load changes, sensitive electronic loads and harmonic generating loads.

Not only conventional APFC are ill-equipped to compensate these types of loads but at a same time generate further operational problems in network by aggravating already poor power quality conditions. This in turn drastically reduces the life span of APFC equipment itself. Repeated investment in solving operational issues and repairing APFC panel becomes regular features of such installations.

Realizing this problem many years back we started offering static solutions for Power Factor Correction. Result is Stat of Art Dynamic Thyristor Switched Activcomp System which offers Dynamic Compensation of Power Factor in Real Time. It is Real Time System where in capacitors are connected and dis-connected in the network at zero current crossing through Thyristor switches. This smooth connection and dis-connection avoids the transients effect typically created by Contactors Switched APFC Systems. Additionaly this system is used for harmonic filtration through tuned and detuned reactor as per system designed.

Activcomp System offers Real Time and Efficient Reactive Power Compensation for fast variable loads, sensitive loads, unbalanced loads, normal loads with moderate to high harmonics. It has Dual Power Factor setting suitable for reactive power compensation on Utility supply and DG supply.

It is now replacing normal Contactor Switched APFC Systems in most of the commercial and industrial installations. Many Activcomp Systems are running successfully all over India and abroad since more than last 15 years. The systems are available in following two configurations :
