What is the purpose of phase failure relays?
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).

A radial system shown in figure below is fed from a supply of 220 Volt. All impedance values are referred to 220V side (3 phase). When a three phase fault occurs at E, relay D will operate with 0.4 second longer than relay at E. Determine TSM (Time Setting Multiple) at A, B C and D by taking discrimination time (DT) equal to 0.4 second, and TSM at C is already set equal to 0.05. The protection data is as given in figure while IDMT relay characteristic is as in table.
