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.
