Inrush Current Limiter

World leading solution in Controlled Switching Devices – CSDs, SynchroTeq technology controls high voltage and medium voltage circuit breakers at the optimum moment to eliminate switching transients.

The SynchroTeq is a manufacturer agnostic and modular solution suitable for simultaneous pole operated (Gang-operated or three-pole operated), staggered pole and independent pole operated - IPO (single-pole operated) circuit breakers. Fitting in new or existing installations, SynchroTeq technology is designed and manufactured in compliance with top industry's standards.

Inrush Current Limiter for HV and MV Power Transformer Energization

Advantages of SynchroTeq Technology:

• Improve the stability and reliability of medium and high voltage electric systems.
