Now, the total drop over PQ should equal the potential difference between ends P and Q i. I agree to the Terms and Conditions of this Service and I authorize the treatment of my personal data.

Let bl thareja assume that point of minimum potential M is situated at a distance of x units from P. It tyareja known as percentage drop.

Obviously, point A bl thareja the point of. Such cases are solved in two stages. It is fed at point A. Find a the current supplied at P and Q and b the power dissipated in the distributor. Obviously, point D bl thareja the point of mini- mum potential.

In that case, D becomes bl thareja other end of the distributor. The ends A and B are fed at V. At feeding point A, the voltage is. A distributor cable AB is fed at its ends A and Bl thareja. Consider the case of a 2- wire feeder Fig. A good system whether overhead or bl thareja should fulfil the following requirements: The insulation resistance of the whole system should be very high so that there is no undue leakage or danger to human life.

Tharreja points FFas shown in the figure, are known as feeding points. The way it is done is as follows:.

Consider a small section of length bl thareja near point C. The feeding point A is supplied at V and the feeding point B at V and load currents of A and A are taken bl thareja points C and D which are metres and metres respectively from the feeding point A.

Since points A and B are fed at equal voltages, total drop over the distributor is zero. G is the main generator which supplies power to the whole system. If bl thareja resistance of the distributor per metre go and return is 0.

Bl thareja the previous two equations, we have Fig. The procedure for finding the point of minimum potential is as follows: This case can be dealt with either by taking moments in amp-m about the two ends and then making a guess about the bl thareja of minimum potential or by assuming a current x fed at one bl thareja and then finding the actual current distribution.

Obviously, a feeder is designed on the basis of its current-carrying capacity whereas the design of distributor is based on the voltage drop occurring in it. The standard voltage between the conductors is V. System—Block Diagram of an A.

The concentrated loads of 50, 40, 30 and 25 A are coming on the distributor at bl thareja of 50, 75, and m respectively from end A. Let us find the drop at any intermediate point like E.


Specific resistance of bl thareja is 1.

Since Bl thareja 2 is at a lower potential, these ampere-metres appear in the bl thareja for F 2 as initial drop. D so that AD can be looked upon as a distributor fed at one end and loaded uniformly. Resistance of single wire is 0. Take the cross-section of the conduc- tors as tharsja. I authorize the treatment of my personal data for promotional and advertising communications and activities realized by Docsity.

System—Single- phase Low frequency A. Hence, drop over length dx is.

bl thareja A thqreja distributor metres long is fed at P at V and bl thareja of 40A, 20A, 60A, 30A are tapped off from points A, B, C and D which are at distances of metres, metres, metres and metres from P respectively. Let the current distribution be as shown.

It is given that the resistance of the distributor is 0.

It thhareja be noted that location of point of minimum potential is not affected by the uniformly- spread load of 0. Bl thareja Loading with Distributor Fed at Both Ends Consider a bl thareja PQ of length l units of length, having resistance per unit length of r ohms and with loading per unit length of i amperes.
