SVC/TCR

Overview

Electrification drives can substantially improve the quality and efficiency of your process or production. Our Dynamic Static VAR Compensators use a proven technology that provides power quality and productivity. Electrification offers both Thyristor Controlled Reactor (TCR) as well as IGBT based Dynamic VAR compensators (D-SVC) for lowering grid interferences due to heavy-duty reactive loads.

Benefits

Flicker with TCR reduction factor ~2:

Dynamic operation that digitally compensates for voltage fluctuation

Modular design:

Based on former HVDC thyristor valve technology for maximum flexibility and optimized footprint

N+1 redundancy:

Continued operation of one or more thyristors having failed

Cost savings in steel plants:

Refractory wear and electrode consumption reduced, increased EAF production up to ~15%

Safety:

Proven standard in separate building room or E-House

Reliability:

Designed to resist severe transients

Quality:

Local grid strengthening and VAR support for higher productivity and power quality, meeting grid code compliance requirements
