I want to use RMS of three-phase voltage as parameter for prediction. I would like to know how to compute the RMS of voltage of a 3-phase motor ? In fact, I have a 1000 samples for each voltage phase ( http://www.mediafire.com/?savomeetkb7frwa ) and I found a formula to ...
When voltage and current are in phase, the kilovolt amperes (KVA) equal the kilowatts (KW), or the power used in the electrical circuit. When voltage and current are out of phase, the KVA are higher than the KW and give the apparent power that has to be multiplied by the power factor...
vmpt2 and so on. the methods for detectingvmos tubes are described below. 1. determine gate g dial the multimeter to r *1k to measure the resistance between the three pins respectively. if you find aword with its feet foot resistance was infinite, and after infinite exchangetest, it is ...
I brought the wire near to the sample and ran a high frequency wave through the sample. Since the sample and the wire are capacitively coupled, I could pick up the high frequency wave on the wire (hooked up to a scope). By then applying a bias the the piezo, I could observe the...
{ zeroCrossDetected = 1; // Determine positive or negative cycle if (adc_samples[i - 1] < adc_samples[i]) { printf("Positive cycle detected\n"); } else { printf("Negative cycle detected\n"); } break; } } if (!zeroCrossDetected) { printf("No zero c...
(IRQ_MASK.EISUM) enabled. The MAXQ3183 would generate an interrupt when the RMS of the four-current vector sum exceeds the threshold. Using the interrupt feature the host is contacted only when necessary, instead of the host constantly polling the vector sum register to determine if an over...
Determine the value of the amps, or "I," you are looking to convert. As an example, assume I is 40 amps. Find a power supply that can provide the amps from step 1 to the electrical load. Connect the power supply to the electrical load. Also connect a voltmeter in parallel with the...
These setpoint values are compared with the instantaneously scanned ATLM signals continuously to determine whether a control rod withdrawal block command or core flow block command should be issued. If an instantaneously scanned and processed ATLM signal value approaches its setpoint, then rod block (...

The wattage doesn't determine the voltage required by a bulb, however. Question: How do you convert horsepower to watts? Answer: There are several different types of horsepower but usually, the conversion for mechanical horsepower or imperial horsepower (hp) is 1 hp = 745.7 watts and for ...
