To convert kW to KVA you say kW/Power factor=KVA. The kVA is a measure of the apparent power while the kW gives the actual power running through the... See full answer below.Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our...
All inverter topologies basically incorporate an oscillator frequency which is then amplified using power devices to high current levels before dumping into the step-up transformer for the final voltage boosting procedures. The current amplifier stage which employs high current devices is where the upgrad...
Even aluminum foil if you can figure how to connect to it. Likes mheslep Aug 7, 2016 #39 SanPhysics 31 1 Thanks for reply Aug 7, 2016 #40 SanPhysics 31 1 SanPhysics said: Thanks for reply Hardy sir can you suggest any method to test output current of transformer so I can...
When an electrical circuit is in use and an appliance of any kind is attached to it, electricians are concerned with four different values; voltage, current, resistance and power. All four values are linked by Ohm's Law, a set of equations that shows the relationships between the main elect...
A 200 kVA, U1N/U2N = 10/6.3 kV three-phase transformer is Yd11 connected, what are the rated currents I1N Consider the core shown in the figure below. a. This core is excited by 40 \ V, 50 \ Hz \ AC power supply. What is the flux density in the core? b. Now, this core is...
The bolting of the two sets of lamination provides some sort of looping effect, generally required for efficient magnetic induction across the core. The winding a single long winding from start to end, as shown in the figure. The center tap from the winding will provide the required approximate...
milliseconds, first determine the duration or period of one vibration by dividing one second by the frequency in hertz. for example, for a 500 hz signal, the duration of one cycle is 1/500 or .002 seconds. to convert this figure to milliseconds, multiply it by 1,000. from the example:...
A good approximation is motor kVA x LRC/FLCMotor kVA = (HP x 0.746)kW / (Power factor x Efficiency) = 1500 x 0.746/0.85 x 0.9 ... assumed values = 1463 kVA, say 1500 kVA(note that this figure will always be approximately equal to the HP)thus for your case motor starting kVA =...
