Dear NascentOxygen,
Using three phase formula,
Power = Voltage x Current x √3
Power = 380V x 9A x 1.732
Power = 5923 VA
OR
Power = 5.923 KVA
Approximately 6 KVA
Hope that this will helpful to you.
Dear Jim Hardy,
Thanks for information, Your provided literature is very easy to understand. Before this i only observed the behavior of derivative that output will not down to 0% even after reaching setpoint if derivative has some value, but not clearly understand about its working inside...
Dear all,
I am working on PID loops now a days and need to know the exact description of PID control.
From TOHO TTM-X04 temperature controller, i learned about P and I, but still i can't understand about D (Differential). As you know that this temperature controller shows manipulated output in...
Dear all,
I have one 22KW motor.
I want to know how much Kvar i need to install for it.
According to my information, i need to check no load current of motor (it is taking 10 ampere at no load), and than take 90% of no load current (90% of 10 ampere is 9 ampere), so install capacitor that...
Dear BilPrestonEsq,
My friend is working on this project. He has designed a speed control circuit of Brushless DC motor. I have seen his designed circuit once, it includes two push buttons that increase and decrease the speed of Brushless DC motor, one LCD that displays motor's current speed...
Dear eximius,
Normally we receive 220Volts in the residence. Here 220V is the RMS(Root Mean Square) value. Approximately 311Volts peak value and 622Volts peak to peak value.
Peak Value(in volts) = RMS value(in volts) x square root of 2.
Peak to Peak Value(in volts) = 2 X Peak Value(in volts)...
Dear Oneoleguy,
You can never produce more power from less power source. The alternator produces alternate energy. This term is used in vehicles where energy is produced by gasoline.
The gears are used to increase torque not power. The power after the gear is always less than the power before...
Dear BilPrestonEsq,
AC induction motor is basically a transformer. The stator of induction motor can be considered as a primary of step down transformer while the rotor of induction motor can be considered as a secondary of step down transformer.
Suppose your rotor is at stationary and you...
Dear Not Newton,
According to my knowledge, your 440volts are generated from two wires of 220volts by shifting their phases 180 degree out. You can confirm it by
1. individually checking these two wires with neutral first(Voltmeter will show 220V in both wires)
2. Checking the voltage...
Dear Tach,
I think series combination of battery is efficient as compare to parallel.
We use parallel batteries to increase current, but if however one battery becomes weak as compare to other battery than more current will flow from the battery of higher potential. Further more if you...
Usually sine wave is generated from the generator coil. The alternate wave is not necessary a sine wave. It can be sawtooth wave or any alternate cycles. The above mentioned formula to calculate rms voltage is for the sine wave.
You can check the rms values of AC voltages. Suppose if you have 220Vrms than it means your AC waveform is a sine wave having positive peak of 311 volts and negative peak of 311 volts. This means peak to peak voltages are 311+311=622 volts.
Peak Voltage = RMS Voltage x square root of 2
Thanks
I have seen your uploaded circuit picture.
Load L1 is driven from the supply and have no connection with inverter. So Load L1 can not be driven from inverter. The reason is that the inverter neutral cable is connected to ground.
Load L2 is driven from the battery and inverter and it can not...
