Re: how to calculate capacitor values 12/02/20098:53 AM Calculation of Required Power Factor The reactive power which is necessary to achieve a desired power factor is calculated by the following formula: QC= P • F QC- Reactive power of the required correcting capacitor P - Active power ...
Formally, calculating short short currents is a complex task because of the many variables involved. For this reason, many engineers use computer programs to calculate the currents. However, you can use a simplified method to approximate the short circuit currents for high voltage 3-phase power di...
To calculate the amps for yourself, it’s useful to know what is 1 kVA in amps. Of course, this depends on the voltage you’re using as well. Let’s say we have a standard voltage (220 V). Here is how many amps you get from a 1 kVA device: You can use this information to c...
Re: how we can calculate transformer capacity in kva? 04/29/2010 Reply 14 2:42 PM Transformer always rated in kVA instead of kW. In your case, The rating of transformer will be considered as Transformer Capacity. If you want to know that how tofind the rating of transformer,Hereis a ...
Calculate power rating in KVA when you know voltage and output resistance. Use the formula:P(KVA) = (V^2/R)/1000 where R is resistance in ohms. For example, if V is 120 volts and R is 50 ohms, P(KVA) = V^2/R/1000 = (14400/50)/1000 = 288/1000 = 0.288 KVA. ...
What is KVA formula? Use the formula:P(KVA) = VA/1000where P(KVA) is power in KVA, V is voltage and A is current in amperes. For example, if V is 120 volts and A is 10 amperes, P(KVA) = VA/1000 = (120)(10)/1000 = 1.2 KVA. Calculate power rating in KVA when you know...
Designing an inverter transformer can be a complex affair. However, using the various formulas and by taking the help of one practical example shown here, the
Calculate your total power requirement by adding up these kW or KVA figures. Click here to use our Power Calculator For equipment rated in amperes, you can convert amps to watts with the following formula: For resistive loads (most common type): Wattage = amperes x volts ...
To calculate your data center cooling needs, you need several pieces of data: the total heat output of equipment, floor area in square feet (ft2),facility designand electrical system power rating. One thing to remember is that some older equipment might have been designed to older ASHRAE cooli...
a. Calculate how many kWh is the amount of energy mentioned above. b. The power taken by the motor from the mains. c. The current taken by the motor from the mains. What SI units are used to measure power? How to convert centimeters to meters with a formula Is a kWh a unit of ...
