With the renowned SynchroTeq®technology from Vizimax, renewable project developers can easily meet stringent grid code requirements, including the IEEE 1547 standards for DER interconnection.

SynchroTeq®is the most advanced controlled switching solution available, designed to minimize switching transients during transformer energization. By precisely controlling the closing operations of circuit breakers at the optimal moment, based on the transformer's residual flux, it effectively reduces the impact on the grid. This patented switching method is versatile, applicable to both independent pole and 3-pole gang-operated circuit breakers, circuit switchers and reclosers, making it a critical tool for modern renewable energy projects.

SynchroTeq® mitigation principle
•Suitable for closing 1-pole operated circuit breakers and 3-pole gang operated circuit breakers and switchgear at the MV and HV level
•Detects the de-energizations and calculates the residual flux in all 3 phases. No need for the opening to be controlled
•Determines and targets an ideal closing instant to limit inrush currents and rapid voltage changes
•Eliminates unwanted impacts of frequent grid connections allowing for a seamless integration of DER to the network
•Reduces the interrupter contact wear of the circuit breaker, circuit switcher and recloser

SynchroTeq® technology
•Patented controlled switching method for optimal results
•Field-proven with thousands of units installed in more than 40 countries on equipment ranging from 4kV up to1,000kV
•Vendor-agnostic solution, fits on any brand of switching equipment
•Natively supports IEC 61850 MMS Ed.2, DNP3 and Modbus
•Maintenance-free solution
•Provides monitoring functions and detects abnormal switching operations
•Results can be anticipated by power studies and EMT simulations
