5–110 745 TRANSFORMER PROTECTION SYSTEM – INSTRUCTION MANUAL
S6 TESTING CHAPTER 5: SETPOINTS
• START PLAYBACK MODE SIGNAL: Select any logic input which, when asserted, initiates
playback mode simulation. This signal has an effect only if the 745 is initially in
prefault mode.
5.8.4.3 Prefault Values
PATH: SETPOINTS S6 TESTING SIMULATION PREFAULT VALUES
• W1 to W3 PHASE ABC CURRENT MAGNITUDE: Enter the winding 1(3) phase current
magnitude (in terms of the winding full load current) while in prefault mode.
• VOLTAGE INPUT MAGNITUDE: Enter the voltage magnitude (in terms of the nominal
VT secondary voltage) while in prefault mode.
