Sensitive earth fault protectionANSI codefunction n°50G-51GF101EquipmentThe test equipment and procedures are the same asthose used for CT earth fault protection.The protection operates according to a particular setof curves (see protection function sheets) and maybe used to measure very low currents via a singlecore balance CT.In addition, a F101/3 relay which switches to 1 whenthere is fault current greater than 15 A, and aninternal relay for disabling protection K857,are available for program logic.The chart of characteristic values followingcorresponds to the curve that is used in distributionsystems, called EPATR B, and it is used as the basisfor calculating protection activation times.Procedurec protection parameter settingv set Iso to the desired value (minimum value for detecting a 0.6 A to 5 A fault)v set T which corresponds to protection activation for 200 A fault currentc test the different points on the curvev preset the injection i and make a note of the valuev stop the injection and reset the chronometer to zerov press reset if required (1)v start up injection and the chronometer at the same timev check the injection value on the ammeter (stability)v Sepam's 2000 output relay stops the chronometerv read the value t measured by the chronometerv compare with the value given in the curve and calculate using the chartsv check the meter and I TRIP0 (1) value on the pocket terminalv stop the injectionv press reset (1) on Sepam 2000 to erase the messages and reset the output relaytTIsoexampleSetting Iso = 1 AT = 0.5 sWhat is the tripping time for injections of i = 2 A and i = 15 A?Use the chart to determine the operating time required to obtain:Test0,6 5 i 15 200A Ii = 2 A ➞i = 15 A➞t = 65.34 x 0.5 = 32.67 st = 12.5 x 0.5 = 6.25 sc status parameter settingv select the 30 A CT value for Ino(1)this function may only be activated if your program logichas been customized.Io time delay (s) Io time delay (s) Io time delay (s)(A) t=1s t=0.8s (A) t=1s t=0.8s (A) t=1s t=0.8s0.6 153.24 122.590.7 137.40 109.920.8 125.00 100.000.9 115.00 92.001.0 106.74 85.391.1 99.76 79.811.2 93.81 75.051.3 88.64 70.911.4 84.11 67.291.5 80.10 64.081.6 76.53 61.221.7 73.30 58.641.8 70.40 56.321.9 67.75 54.202.0 65.34 52.272.5 55.79 44.633.0 49.04 39.233.5 43.96 35.174.0 40.00 32.004.5 36.80 29.445.0 34.15 27.325.5 31.93 25.546.0 30.01 24.016.5 28.25 22.607.0 26.29 21.037.5 24.58 19.668.0 23.08 18.468.5 21.75 17.409.0 20.58 16.469.5 19.51 15.6110.0 18.56 14.8511.0 16.91 13.5312.0 15.54 12.4313.0 14.38 11.5014.0 13.38 10.7015.0 12.50 10.0016.0 11.74 9.3917.0 11.06 8.8518.0 10.46 8.3719.0 9.93 7.9420.0 9.44 7.5525.0 7.60 6.0830.0 6.36 5.0935.0 5.48 4.3840.0 4.80 3.8445.0 4.29 3.4350.0 3.86 3.0955.0 3.53 2.8260.0 3.24 2.5965.0 2.99 2.3970.0 2.79 2.2375.0 2.60 2.0880.0 2.44 1.9585.0 2.30 1.8490.0 2.18 1.7495.0 2.06 1.65100.0 1.96 1.57110.0 1.79 1.43120.0 1.65 1.32130.0 1.53 1.22140.0 1.41 1.13150.0 1.33 1.06160.0 1.24 0.99170.0 1.18 0.94180.0 1.11 0.89190.0 1.05 0.84200.0 1.00 0.80>200 1.00 0.80Sepam 2000 - Testing1/25
