MTS Alstom Metropolis [Alstom OPTONIX MG 1500 IGBT–VVVF] inductor coil recording 3

Recorded 4 January 2023 North West line, Cherrybrook → Epping Set number: 26 Despite the fact that this is the longest interval between 2 stations of the line, the train didn't reach full speed and therefore didn't decelerate from synchronous 1-pulse mode. Pattern: async 300Hz→500Hz→sync 21 pulse→15 pulse→11 pulse (Selective Harmonic Elimination)→7 pulse (SHE)→5 pulse (SHE)→wide 3 pulse→1 pulse #モハラジオ #Alstom #IGBT #VVVF #sydneymetro
