Answer Posted / k.prakashchandra
The metal sheath is earthed or unearthed. 1.9/3.3 and
3.8/6.6 are phase/ line voltages and are 3 core
cables.3.3/3.3 KV means 2 core cable for single phase
supply ,as neutral is present earthing is not necessary.UE
means unearthed E means earthed

A commercial Building is designed with 14th floor levels with indoor substation of three phase transformer with rated capacity of 1000 Kva.The transformer delivered 65% of its rated capacity at 0.67 power factor lagging.Because of low power factor, the power customer was penalized and certain cost was charged accordingly based on every point percentage lower than 85%.This situation may repeatedly happen on the succeding energy bills of power customer.The power customer is desired to improve its historical power factor of 0.67 lagging and no further penalty be impose by the local power company on the next bill.
