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). The figure shows zone 1 distance time curves for a 60 Hz system at nominal system
frequency.
