Unchoked power factor correction
for use in networks with low harmonic load
Areas of application
- Automatically controlled central compensation
- For use in networks with low harmonic loads
- Power converter output (non-linear loads) < 15 % of the connected load
- Total harmonic distortion of THD-U < 3 %
- No common use in networks with choked capacitors
- Not for use with critical ripple control systems in the 270 to 425 Hz range
Optimized, thermal design
The enclosures are forcibly ventilated by a raised roof and a filter fan in the lower section. Particularly large systems also have a roof ventilator. The main heat source, the throttle, is positioned precisely in the air flow.
Low losses (PV)
Janitza’s power capacitors have dielectric losses of just 0.2 W/kvar. The total power loss is 0.5 W/kvar.
Self-healing
Due to their design, the capacitors are self-healing. In the event of a localized short circuit, the fault burns away and blows out the arc. This ensures high long-term stability.
Long service life
The capacitors are designed for a long service life in several respects. The low losses and optimized thermal design minimize the thermal load. In addition, self-healing ensures that the capacitors remain operational even after quasi-short circuits.
