Supervision task for interruption capability on CB
For the supervision of the circuit breaker, the sigma_Iy function is provided so that the broken
current quantities at respective tripping are accumulated. Thereby, the user can monitor the
interrupting capability using the sigma_Iy function. When trip commands are issued, the
sigma_Iy function monitors the maximum current (I at CT primary) in every occurrence of the
fault, the sigma_Iy function accumulates each maximum fault current powered by a parameter
‘y’. Thus, the user can find a synthesized broken current value using the sigma_Iy function.
Displaying error message founded by the sigma_Iy function is shown in Table 10.4-1.

Note:
The implementation of particular features is dependent upon the selection of
hardware and the configuration of functions. Several IED models do not support certain
features. To determine whether a particular feature has been implemented within an IED,
identify the IED ordering number; and check the order number for the “G&T position” whilst
referring to the comparison table below. For more information, see
Appendix: Ordering
