Valve Position (V) Open V m e PV Close SP c) High Gain, KC > 1. Figure 1-12. Proportional control PV 0% 100% As these graphs show, the amount of valve change (∆V) for a given error can vary substantially. A one-to-one relationship is shown in Figure 1-12(a). In that example, the control valve

Design specification High voltage overhead power lines must comply with several requirements. We need to consider various factors for the design specification, mechanical and electrical and also the sites where the cables will be fixed. The site is very important because its span varies enormously depending on the nature of the terrain and climate. Also important to the requirements are the lowest electrical resistance (to cut down losses), safe clearance over the ground, adequate strength

radial (north). As the angle measured from the 0° radial increases, the phase of the variable phase signal lags the phase of the reference signal by the number of degrees of the angle from 0°. The reference and variable phase signals, which are 30 Hz voltages, are carried by RF to make radio transmission and reception possible. The VOR receiving equipment must separate the 30 Hz reference and variable phase signals from the RF carrier and compare the phase of the two signals. The phase difference is indicated

ON Semiconductort Wideband Linear Four Quadrant Multiplier The MC1495 is designed for use where the output is a linear product of two input voltages. Maximum versatility is assured by allowing the user to select the level shift method. Typical applications include: multiply, divide*, square root*, mean square*, phase detector, frequency doubler, balanced modulator/demodulator, and electronic gain control. • Wide Bandwidth • Excellent Linearity: 2% max Error on X Input, 4% max Error on Y Input

this equipment away from humidity. Lay this equipment on a reliable flat surface before setting it up. The openings on the enclosure are for air convection hence protects the equipment from overheating. Do not cover the openings. 6. Make sure the voltage of the power source and adjust properly 110/220V before connecting the equipment to the power inlet. 7. Place the power cord such a way that people can not step on it. Do not place anything over the power cord. 8. Always Unplug the Power Cord before

OF FUNCTIONING Consist to combine one or two electric motor and combustion engine to propel the vehicle. It’s the electric motor that operates the stake in movement of the vehicle up to a speed of 25km / hour as it moved off. When the speed is higher or a strong acceleration is asked, the combustion engine takes over and begins working. Very strong acceleration, we have both engines which work together. During braking and deceleration, significant amounts of energy are recapturing that are normally
