2-What is the amount of power saving in the AM-DSB- SC, when compared to other types of AM systems?

Q3. In a % differential scheme, figure shown below, the two CTs have nominal ration of 100:1. The CT errors for a through fault current of 5000 A are as following: CT1 CT2 Ratio error: 10% 10% Phase angle error: 5% -5% Compute following: i) The spill current of the OC relay in the spill path. ii) If the relay is 50% biased, examine whether relay will trip or remain stable CT, CT Ir CB C.B. メx Egu inder Ne

What is the Continuity Test?

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

What is the significance of relay protection in power systems?

Tring to solve this MOSFET question but not sure how. Need to find the missing components value. (Given Answer : RD = 4.27 kohm R1=28.075 kohm R2=8.77 kohm)

Can we select components voltage references randomly in order to write KVL? Why?
