Short-Circuit Testing and  Certification of Inverters  

AdobeStock_167572213.jpeg

The Short-Circuit Testing and Certification (SCTC) scheme comprises a series of comprehensive assessments of the Short Circuit Current Contribution of Inverters intended for integration into the Distribution System. In order to demonstrate that it is capable of minimizing the effects of Short-Circuit Current Contributions in accordance with the specifications set out in these Guidelines, the Inverter must undergo the requisite certification process.

 

The certificate is valid for an indefinite period, provided that no modifications are made to the product that could potentially impact the performance of the Inverters in mitigating Fault Current Contributions. Certificate Holders are obliged to adhere to the established certification standards, including both hardware and software modifications. Failure to comply with these standards may result in the suspension of certification, and in the event of continued non-compliance after a designated period, the certification may be revoked.

 

This section provides a detailed description of the SCTC scheme for Inverters for DN. The document serves to direct all pertinent parties through the certification process.
