CHAPTER 5: SETTINGS GROUPED ELEMENTSL60 LINE PHASE COMPARISON SYSTEM – INSTRUCTION MANUAL 5-1975Phase comparison signals are important for the analysis of 87PC operation. As such, they are recorded in oscillography. Alist of the 87PC channels recorded in oscillography is shown as follows.Table 5-26: 87PC oscillography channelsSee the Application of Settings chapter for calculation examples for the phase comparison elements.CFG file label DescriptionX1: IA Phase A of the F module CT bankX2: IB Phase B of the F module CT bankX3: IC Phase C of the F module CT bankX#: IA Phase A of the X module CT bankX#: IB Phase B of the X module CT bankX#: IC Phase C of the X module CT bank87PC BKR1 Current Effective mixed operating signal of breaker 187PC BKR1 POS Positive current pulse for the first breaker87PC BKR1 NEG Negative current pulse for the first breaker87PC BKR1 FDL Low-set fault detection for the first breaker87PC BKR1 FDH High-set fault detection for the first breaker87PC BKR2 Current Effective mixed operating signal of BKK287PC BKR2 POS Positive current pulse for the second breaker87PC BKR2 NEG Negative current pulse for the second breaker87PC BKR2 FDL Low-set fault detection for the second breaker87PC BKR2 FDH High-set fault detection for the second breaker87PC POS Positive current local pulse for both breakers87PC NEG Negative current local pulse for both breakers87PC FDL Low-set fault detection for both breakers87PC FDH High-set fault detection for both breakers87PC Rx1P Voltage Received pulse (voltage) on channel 1P87PC Rx1P Received pulse on channel 1P87PC Rx1N Voltage Received (voltage) on channel 1N87PC Rx1N Received pulse on channel 1N87PC Rx2P Voltage Received pulse (voltage) on channel 2P87PC Rx2P Received pulse on channel 2P87PC Rx2N Voltage Received pulse (voltage) on channel 2N87PC Rx2N Received pulse on channel 2N87PC POS Aligned Aligned (delayed) local positive pulse87PC NEG Aligned Aligned (delayed) local negative pulse87PC Rx1P Aligned Received and conditioned pulse on channel 1P87PC Rx1N Aligned Received and conditioned pulse on channel 1N87PC Rx2P Aligned Received and conditioned pulse on channel 2P87PC Rx2N Aligned Received and conditioned pulse on channel 2N87PC POS Int Input Input of the positive integrator87PC NEG Int Input Input of the negative integrator87PC POS Integrator Positive integrator in (degrees)87PC NEG Integrator Negative integrator in (degrees)87PC Trip CT/VT module to CPU trip pulseTx Pos Transmit signal per 87PC logicTx Neg Transmit signal per 87PC logicFDH Aligned
