RC filter bank systems are high-voltage transient damping solutions designed to suppress chopping currents and transient overvoltages that occur when high-power shunt reactors are switched in or out.
 

By absorbing the high-frequency oscillations that can result from MV reactor switching, Enersolix RC filter systems

• protect the network,

• and isolate transformer tertiary windings from sudden voltage stress.
   

What Does It Do?

• Damps chopping currents during MV shunt reactor switching

• Suppresses insulation stress caused by transient overvoltages

• Protects the tertiary windings of large transformers from high-frequency stress

• Extends the dielectric life of system equipment

• Prevents arcing and resonance effects during switching
   

Technical Specifications (General):

• Voltage level: 6.3 kV – 36 kV

• RC values: resistor and capacitor combinations calculated for each application

• Installation: inside metal-enclosed panels or open installation

• Cooling: Natural air

• Protection: Fuse-protected design

• Standards: IEC 60071-1, IEEE C57.16, IEC 62271-110; designed to site transient analysis
   

Applications:

• Systems with MV shunt reactor switching

• Tertiary winding protection in MV substations

• Transient suppression in MV power plants

• Voltage regulation and balancing systems

• Metal-enclosed MV switchgear systems
   

Why Enersolix RC Filter Systems?

• Damps transients quickly and in a controlled way

• Prevents the stress that chopping currents put on transformers

• Application-based engineering ensures full system compatibility

• Maintenance-free, long-life and safe design

• Works together with MV shunt reactor compensation solutions
   

By neutralising high-frequency transients in your MV systems, Enersolix RC filter solutions extend equipment life and minimise the risk of failure.
