Waves Introduction For this experiment‚ the use of equipment such as oscillators and function generators were used in order to calculate forms of AC waves. Waves are visual representations of the variation of a voltage or current over time and are used in many applications throughout technology. Aim The aim of this laboratory was to be able to measure the voltage in a circuit over a specific time using equipment such as an oscilloscope‚ and using it to look at the SINE wave that is

Fluke 117; True RMS Multimeter review The Fluke 117 true Rms is a member of the Multimeter fluke series. It is a very unique device with distinctive features. This is the main reason why its stands out from the rest of the Fluke Multimeter series. Fluke 117 can be used in very high demanding settings and buildings such as schools and hospitals among other commercial settings. This Fluke Rms Multimeter is not only capable of measuring frequency and capacitance but also resistance‚ voltage and current

company supplies pins in bulk to a customer. The company uses an automatic lathe to produce the pins. Due to many causes-vibrations‚ temperature‚ wear and tear‚ and the like-the lengths of the pins made by the machine are normally distributed with a mean of 1.012 inches and a standard deviation of 0.018 inch. The customer will buy only those pins with lengths in the interval 1.00 ± 0.02 inch. In other words‚ the customer wants the length to be 1.00 inch but will accept up to 0.02 inch deviation

The procedure is repeated for different values of voltage with the same wire and in each case the ratio V/I is calculated and the mean value of R is found. Similarly the resistances of other materials are calculated. 2) TO STUDY THE VARIATION OF RESISTANCE WITH LENGTH OF THE CONDUCTOR To study the effect of length of wire on resistance of the material

A UPQC has the same structure as a UPFC. It can inject current in shunt and voltage in series simultaneously in a dual control mode. Therefore it can perform both the functions of load compensation and voltage control at the same time. The UPQC must also inject unbalanced and distorted voltages and currents and hence its operating characteristics are than that of a UPFC. Furthermore their operation philosophy is different. The UPQC is also an (PQ) enhancement device. UPFC and can operate under

Among these problems Voltage Sag & Swell are identified as major concern to the electrical consumers. Voltage Sag is one of the most occurring power quality problems that cause severe problems and losses to industry.
