Share 'GE Multlin SPM Application to Prevent Power Factor Trip during Voltage Dip'
I have a 2500 Hp; 4000 Volts; 240 RPM; 0.87 P.F. synchronous motor with GEMultlin 269+ & SPM protection that trips on Power Factor Fault from the SPM when another motor (induction motor) load is applied. The induction motor is connected to the load through an air clutch and once engaged, the voltage dips enough to cause the trip. The synchronous motor load has to operate before the induction…
