Operating experience shows that, in addition to shunt capacitor itself defects will cause the accident occurred, harmonic on the operation of shunt capacitor will cause an accident. Based on the harmonic on shunt capacitor damage and limit the harmonic measure, and the capacitor wiring options are briefly introduced. Keywords: capacitor harmonic connection mode of capacitor group
