2 4095how calculate cable size in squre mm, when the load is given by in kw? do u have current rating chart of elctrical cables?
4 10963I have three phase 400 KW,390 A MOTOR.For this motor which type of Cable is required....specifically rubber cable required. Can anyone help me..
5 7583Why celling fan rotates in anticlockwise direction and table fan in clockwise direction ? Give technical reason.
5 16434how can we phase identification in a distribution line,how we recognise that which phase is coming for a house hold connection.help me............
1589Which are resistive loads & which one are inductive loads : Refrigerator, Split air conditioner, ceiling fans, well pump, fluoresecent bulbs, T.V, CRT Monitors, Adsl Routers, C.P.U, Printers, Deep Freezers, Speakers, DVD Players, Microwave oven etc. ? Output Power for these Appliances Would be same like this : P = V * A * P.F Or would be changed ? thanks
3421Are Refrigerators & Deep Freezers the Inductive load ? How to calculate the Power Factor & hence the Output Power for them ?
4632How can we calculate the power factor of an electrical appliance ? Is there any formula ? Is there any meter around to calculate it ? And how to use that meter ? thanks

What happen when neutral point connected to core balance current transformer? (Neutral point of an alternator of a 180KVA DG. Neutral point connected to CBCT means enter to the CBCT)
Hi, Next week Iam appearing RRB exam for section engineer. So help me to get modal question papers for this position. Iam very thankful to you. Whether question will be fully techanical format or general form. Please give me a details regarding this exam.
solar inverters was not connected to the nuteral link .this nutwral possible to any other systems
how can we select the appropriate VCB ?
Is there a possibility to use such a treshold voltage for the NMOS part of a CMOS circuit that during the switching it will start conducting only after the PMOS part will be already closed, by this eliminating the leakedge current? Please note, I'm not asking about the well bias in standby mode, but about the "antileakedge" measures during normal operation.
Can we check ELCB constantly from R1 to R8 phase in 1 no DB?
while doing high potential for 11KV 3 core cable how much leakage current will obtain?, what will be acceptance value?
