A 115-kV transmission line has a positive sequence impedance of 28280 ohms (primary). a. You are to set a Zone 1 mho-type phase distance (21-1) relay to cover 85% of the line and a Zone 2 (21-2) relay to cover 125% of the line. For better resistive fault coverage, the relay maximum reach angles are set to 60. Determine the required relay reach settings (at the relay reach angle). Instrument transformer ratios are given as: CTR = 1200/5A and VTR = 1000/1V. b. Assuming a lagging power factor limit of 0.87, how much load (in primary MVA) can the Zone 2 relay carry at 1.Opu voltage? Don't worry about any additional safety margins or reduced voltage conditions
