Hydraulic pumps and pressure regulation
A hydraulic pump (Figure 2.1) takes oil from a tank and delivers it to the rest of the hydraulic circuit. In doing so it raises oil pressure to the required level. The operation of such a pump is illustrated in Figure 2.1a. On hydraulic circuit diagrams a pump is represented by the symbol of Figure 2.1b, with the arrowhead showing the direction of flow.
Hydraulic pumps are generally driven at constant speed by a three phase AC induction motor rotating at 1500 rpm in the UK (wi ....etc

Based on closed form expressions for the power frequency voltages and currents in a typical distribution network, the voltage regulation VR at any time point during the day could be evaluated. It will depend primarily on the network configuration, the daily load curve, the load density and its power factor as well as level of the reactive power compensation.

The computed at a certain time?t? can give a useful indicator for the voltage constancy over the network at that time point. The concept of ?Global Voltage Regulation? is introduced. Th ....etc

ABSTRACT
The performance of any machine can be analyzed with reference to parameters like power factor, total harmonic distortion, voltage regulation, etc. These parameters alter when a machine is subjected to different loads. Depending on the load connected to the system, the voltage and current waveforms are varied. Due to the effect of harmonics, distortion of waveforms from sinusoidal to non sinusoidal is c ....etc

Basic Rules and Tips in Group Discussions GD TIPS AND SCORING POINTS



1. Always be the initiator and concluder of the GD then being a participant.

2. But if you are particaipant always try to be the most vianl/key participant.

3. put points firmly and always try to get others support too.

4. if you find that the discussion os going offttrack then never loose an oppurtunity to bring it back to straem this is the best point to score max.

5. try to keep l ....etc
