PCS+'s Capacitor Bank CTs purpose and accuracy

[Mannguyen]

Hi All,

Please advise me on the questions from many customers when we offer the Active Harmonic Filter PCS+:

- What is the purpose of the CTs installed in the Cap. Bank Bus? Is it an option or mandatory?

- A new customer who we offer to, as the attached picture. The question on the SLD of CTs connection is: What is the accuracy of current detection since the discrepancy of CT's amp. rate and Cap. Bank bus Breaker's amp. rate (5000A vs 2500A rates)?  

I appreciate it if you kindly share the SE documents that have clarified the above-mentioned questions.

Thank you all in advance
