TRIPAC installations
General
TRIPAC systems are thyristor-controlled, fully automatically controlled, with reactor-based reactive current compensations equipped with high-quality, self-healing dry capacitors.The use of thyristors instead of switch contactors is recommended for very dynamic grid conditions with fast load changes or in grids with unstable voltage conditions.
Special features
- Reactive power is compensated in real time
- Zero current switching of the capacitors increases their service life
- No mechanical wear of switchgear
- Thyristors are maintenance-free
