2.4.1 PROTECTION ELEMENTS
The operating times include the activation time of a trip rated form-A output contact unless otherwise indicated.
FlexLogic operands of a given element are 4 ms faster. Take this into account when using FlexLogic to interconnect
with other protection or control elements of the relay, building FlexLogic equations, or interfacing with other IEDs or
power system devices via communications or different output contacts. If not specified, the operate times given
here are for a 60 Hz system at nominal system frequency. Operate times for a 50 Hz system are 1.2 times longer.
