2 4668What is the maximum allowed kwa through 2.5mm cable. Electric company installed 2 electric meter at my premises . Two jumper wires of 2.5 mm are used to connect . 2 single phase meters with allowable load 6 and 3 kwa. These jumper wires are taken from a 3 phase electric meter. Meters are in open Sun. What max load these wires can take.

2120I am new guy as an electrical engr. in a 100MW HFO based power project. I am in operations division. I have noticed from last few days, my supervisor sends the last 24 hours energy generation calculation to my plant manager. I have noticed, he calculated last 24 hour's generated energy differences in KWH then he multiplied it with a multiplying factor 960. for example: total difference =2.685 KWH*960= 2577.6 MWH. but he does not not know what is multiplying factor 960?? can anybody explain it??

2992Dear Friends, Need your help for connecting APFC panel, Quotation : I have 2 No’s 1000 KVA Transformers, both transformers are having separate APFC panels, ( Tr-1,400KVAR, TR-2,450 KVAR) Now I want to stop One transformer, present load is 650Amps, Max, So One transformer is enough, I have switched OFF TR-1, but PF is not maintaining properly, its 0.5, So now I want to connect TR-2 APFC also in TR-1 Loads, Can any one answer for my Quotation with drawing, how to connect TR-2 APFC panel in TR-1 Loads,
