- 5.1 Determine the three zone settings for the relay Rab in the system shown in Figure 5.26. The system nominal voltage is 138 kV, and the positive sequence impedances for the various elements are given in the figure. The transformer impedance is given in ohms as viewed from the 138 kV side. Assume that the maximum load at the relay site is 120 MVA, and select a CT ratio accordingly. The available distance relay has zone 1 and zone 2 settings from 0.2 to 10 2, and zone 3 settings from 0.5 to 40 2, in increments of 0.1 2. The angle of maximum torque can be adjusted to 75° or 80°. Remember that the zone 3 of the relay must back up the line BC, as well as the transformer.

Do you suppose that there is a combination of bias and transfer function that might allow this? i. Is there a transfer function from Table 2.1 that will do the job if the bias is zero? ii. Is there a bias that will do the job if the linear transfer function is used? If yes, what is it? iii. Is there a bias that will do the job if a log-sigmoid transfer function is used? Again, if yes, what is it? iv. Is there a bias that will do the job if a symmetrical hard limit transfer function is used? Again, if yes, what is it?arrow_forwardE2.2 Consider a single-input neuron with a bias. We would like the output to be -1 for inputs less than 3 and +1 for inputs greater than or equal to 3. i. What kind of a transfer function is required? ii. What bias would you suggest? Is your bias in any way related to the input weight? If yes, how? iii. Summarize your network by naming the transfer function and stating the bias and the weight.

The slew rate of an amplifier can cause signal distortion at its output if wrongly chosen. State the criterion for selecting the slew rate of an amplifier to avoid signal distortion. A step signal of 5 mV is applied to an inverting amplifier shown in Figure 2, which has a slew rate of 0.05 V/us. Estimate the time required for the output voltage of the amplifier to reach within 10% of its final value. If the input to Figure 2 is a sinusoidal signal of 0.02 sin(2πft) V, determine the maximum frequency that can be applied to the circuit without causing signal distortion due to the limitation of its slew rate (0.05 V/µs). In order to minimise the output offset voltage of Figure 2, a compensating resistor should be added to Figure 2. Draw a modified circuit diagram that includes the compensating resistor. Determine the appropriate value for the compensating resistor.
