DESCRIPTION
twice in each swing cycle, and a short setting ensures continued PSB pick-up, to ride through the gaps.
OST Mode 3D 23 OST Disabled
OST Predictive Trip
OST Trip
To enable (activate) or disable (turn off) Out of Step protection. This setting (and all related settings below) is invisible if PowerSwing Block is
disabled in ‘CONFIGURATION’ column.
If ‘OST Trip’ is selected, relay will operate after Tost time delay if the measured positive sequence impedance has passed the Z6-Z5 region
slower than 25 ms (@ 50 or 60 Hz) and if the polarity of the resistive component has changed between entering and exiting zone 5.
If ‘Predictive OST Trip’ is selected, relay will operate after Tost time delay if the positive sequence impedance has passed the Z6-Z5 region
faster than 25ms but slower than ‘Delta t’ set time.
If ‘Predictive & OST Trip’ is selected, it will operate if any of two above criteria is satisfied.
