Overview
In the “Capacitor bank” function group, all the functions that are necessary for protecting and monitoring a capacitor bank can be used. Some of these functions are exclusively used for protecting capacitor banks, and others are universal standard functions which can be used for other protected objects as well.
For more detailed information on “Capacitor bank” function group, refer to SIPROTEC 5 devices, V8.30 & higher manuals.
