CIL,
1 3816a high voltage electric line for showing a blinking rod but connected a single line..wht is the rods name...and explain its working
1489i have ht transformer of 142 kva with air cooled facility,having secondary voltage 7850volt, and secondary connected full way bridge rectifier .i faced the problem repeatedly that transformer one coil and rectifier diode of two phase was burnt two times. i checked all the secondary ckt. no any short ckt found,then what will be the cause side
2 2772in HT service 3ph 4 wire service Y-phase voltage shows zero . whether it is meter fault? or what be the reason ? if y-ph voltage zero ,can current is recorded? reasons for failure?
1868According to Shockley equation, the I – V characteristic of a diode is approximated by I = IS [ exp (nVD / VT) – 1 ]. For silicon, let the reverse bias saturation current IS as 0.000000000001. If n is ideality factor with value of 1.5, VT as thermal voltage drop of 0.026 V at room temperature, what is the value of current I that passes through the silicon diode in the heater of evaporator when the forward voltage drop VD = 0.026 V? Please take note that exp is the exponential function with e(1) = 2.718, e(2) = 7.389.

I just want to convert the voltage into current i.e. suppose I have 750V & 1A AC power then I want to convert it into 12V & 62A DC power only difficulty is that I don't want to use the tranceformer. Simply to say, I want to make the step-down without using tranceformer. Please, give me some ideas. And also I want the relation between Magnetic Induction & Weight of the body can be levitated. Or I can say, how much of magnetic induction requires to lift 500gms weight? I am heartily thankful to you.
iam using DM 3251 voltmeter(1 percent accuracy)for 11KV system PT ratio is 11KV/110V.can anybody explain what is the max and min voltage deviation.
