SWING DETECTION (PSD) 4.1. PSD REACH TEST MEASUREMENT Item Description Checked 1 out from Freja attached. Where: RLdFw = KLdRFw * RLdOutFw = KLdRRv * RLdOutRv TIMING TEST: Check The Operating Time (TP1) Type of fault Tp1 setting ms Tp1 actual ms 3 phase 40 TP1: it is the smallest time can be passing from outer boundary to inner boundary of Power Swing Chars. to detect PSD Start GENERAL MODE, SEQUENCE, 3 STAGES. 1ST STAGE: Normal Load, 3phase Vr & Ir, outside the outer zone area 2nd STAGE: 3phase V&I to get the impedance inside the PSD zone (I=Ir & V/I<Zouter and T =Tp1).
