GROUND 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).
