Making Any Installation Possible

Retrofit installations may not happen before defining a comprehensive add-on solution that does not interfere with existing connection schemes. A considerable portion of switchboards is designed with a single set of CTs. As a result, the same CT set is to be shared by protective relays and one or all of the following devices: power meter, power quality analyzer, fault recorder. Adding a new power meter, power quality analyzer, fault recorder, or upgrading the obsolete one is a considerable challenge, due to a high risk of main breaker trip.

Since disabling protective relays is never a good idea and scheduled power outage can be extremely undesirable, SATEC has developed a cohesive solution. The solution allows to avoid any impact on protection relay connection circuits by use of external split core CTs coupled with specially developed SATEC Add-On device line.
