CURRENT WAVEFORM DISTORTION AT 25 KV SINGLE PHASE SUPPLY POINTS TO BRITISH RAILWAYS

The 132 kv current taken at the 132/25 kv substations supplying the British Railways 25 kv 50 Hz traction system is unbalanced, being single phase connected across two 132 kv system phases, and the waveform is distorted i.e. it contains harmonics. Both conditions can cause difficulties on the public supply network and require continuing investigation, since future expansion of the BR 25 kv electrified system is likely. However, this paper deals only with the harmonic aspects of the problem, the unbalance effects.
