Figure 1 shows a common and simple power circuit breaker control schematic. You are asked to draw an equivalent logic diagram using the well-known symbols shown in Figure 3. In

order to complete the scheme, use a simulated representation of the actual circuit breaker as shown in Figure 2. Assume that both, the tripping coil and the closing coil have associated contacts and that they operate over an auxiliary relay (used to simulate the circuit breaker) called 52, which has normally open (52/a) and normally closed (52/b) contacts. CS/T and CS/C are spring self-reset switches as explained in class. a) Explain the scheme shown in Figure 1. Put special emphasis on the function of auxiliary relay Y. b) Draw the logic diagram using logic gates symbols as explained in class
