LMU stands for Line Matching Unit used in Power Line Communication (PLC), LMU & LMDU used as Coupling Devices. If the coupling is Phase-Phase it requires LMU & LMDU. If the coupling is Phase-Ground LMU is enough for Power Line Communication.

we have two generators different capacity on 15 MW and other 6MW at 11 KV , 15 MW gen. bus short level current 40KA,and 6MW short level current 25KA,, length of cable 100MTR between 6 MW from 15MW gen. for bus coupling . kindly tell any one can we use both NGR OR one NGR from any GEN. BOTH NGR has diff. rating. Tariq pakistan
