You are working for a company called International Road Dynamics' located in Saskatoon Saskatchewan on an improved over height vehicle detection system. The new system has a sensor when the vehicle height is detected above 5 meters. OVER HEIGHT LOAD WHEN LIGHTS FLASH If the height > 5 meters we want to flash the warning light (single light) for 0.5 second every 0.8 seconds. If the vehicle height is below 5 meters the light is off. The height sensor provides a +8V output pulse, with a very low source resistance. Assume the light control is via a 12V 100 mA relay. You have +/-12V supplies available to you. Using parts and circuits covered in the lecture and lab, implement a solution to this problem. NOTE. Show all steps and work involved in developing your design

Q14) An assembly line has 3 fail safe sensors and one emergency shutdown switch. The line should keep moving unless any of the following conditions arise: (i) If the emergency switch is pressed (ii) If the senorl and sensor2 are activated at the same time. (iii) If sensor 2 and sensor3 are activated at the same time. (iv) If all the sensors are activated at the same time Suppose a combinational circuit for above case is to be implemented only with NAND Gates. How many minimum number of 2 input NAND gates are required?

The system having ±0.5% of F.S.D if the full scale deflection is 50 units, then accuracy is _____ a. ±0.25 b. ±1 c. ±0 d. ±0.5

In a signal phase, pedestrians are allowed to cross the street walking in the same direction as movements 2 and o. The distance from one side of the street to the next (length of the crosswalk) is 72 ft. The width of the crosswalk is 9 ft. What minimum green time should be set aside for 12 pedestrians (both directions combined) to cross per phase? Round your answer to the next second. Suggest a walk interval, pedestrian clearance interval, and buffer interval.

FIrst 3 question answers are give below answer the last two partsanswers: 1) relay at C (CT ratio) = 40 : 1     relay at B (CT ratio) = 60 : 1     relay at A (CT ratio) = 40 : 1 2) TMS/A = 0.711 3) top = 1.48 sec ( relay will operate as per the fault current level.) i) Design appropriate CT ratios for CTA, CTB, and CTC. (ii) Estimate time of Operation for all three relays for maximum value of fault current to maintain the selectivity. (iii) Determine TSM for relays at bus A and B for maximum fault current. (Use the standard formula for IDMT relays for these calculations.)  (iv) Also use the standard curves for IDMT relays shown in Figure 2 to select TSM for relays at bus A and B for maximum fault current. Compare results obtained in (ii) and (iv).  Verify the design to ensure that selectivity is maintained at minimum fault current for the fault in the same zone

An overcurrent relay set to operate at 8A is connected to a multi ratio current transformer (whose excitation curve is given in Figure 2 below) with CT ratio =100:5, Zs= 0.082 02 and ZB = 0.8 0. (a) What is the minimum primary current at which the relay will operate? (b) Will the relay detect a 180A fault current on the primary side? (c) Determine whether or not the CT will saturate when the relay current is 8A. Compute the percentage CT error. (d) What is the CT knee voltage poin
