Designed specifically to comply the customer needs, we use high quality components, engineered and assembled to provide optimal performance and unparalleled reliability.

water-cooling-system

Water cooling system

Compact and high efficiency cooling system.Two options for cooling are available. Water/water with external loops or water/air type with extra fans.

protecction-and-control

Protection and control

Advanced digital control system with multiple customizable functions. Protection modules can be personalized to fit specific customer requirements. Remote monitoring systems are available.

SVC Operating principle

An SVC is connected to the system as shown in the following figure. The capacitor banks provide the reactive power. The thyristor-controlled reactor (TCR) will consume the reactive power that the load doesn’t require. This is accomplished by controlling the triggering angle of the thyristors. The control system determines the reactive power compensation required by comparing the reactive power of the bus against the reactive power target value in the SVC controls.
