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, operate times are given
here for a 60 Hz system at nominal system frequency. Operate times for a 50 Hz system are 1.2 times longer.

PHASE DISTANCE OPERATING TIME CURVES
The operating times are response times of a microprocessor part
of the relay. See output contacts specifications for estimation of
the total response time for a particular application. The operating
times are average times including variables such as fault inception
angle or type of a voltage source (magnetic VTs and CVTs).
