The tools used by design offices are WACK: here’s the proof!

At the beginning of this year, we received a long email from Elina, who expressed her dissatisfaction with the digital tools offered by the manufacturers and the SSIs to help the design offices to analyze and put a cost on technical specifications.

We decided to publish it as is. So, do not hesitate to react by posting a comment in the dedicated section below!

Current transformers are the interconnection element between the power system and all measurement devices like protective relays. CTs actually lower the value of the primary current to a nominal secondary level in order to be used by meters, protective relays, meters, and monitoring devices.

Here’s a list of the impacts of current Transformers errors on protective relays written by Electrical Engineer Mile.
