Introduction Relay:
Zones limit The nominal shape of the 7SA610 characteristic curve is shown in the following image.
7SA610 characteristic curve It is a characteristic polygonal curve with the following features: Directional-1: - 45°; Directional-2: 135°; DOBLE ENGINEERING PVT LTD, 305-SAKAR, OLD PADRA ROAD, VADODARA-390 015 DOBLE ENGINEERING COMPANY, 85-WALNET STREET, WATERTOWN, USA www.doble.com

Settings are: -Æ Values X1, X2, X3,X1B or X1L; -Æ Values R1, R2, R3, R1B or R1L for multiphase faults -Æ Values R1E, R2E, R3E, R1BE, R1LE, for single phase faults. .Trip time 1ph: T1,T2, T3; for trip time with mono phase faults. .Trip time >1ph: T1,T2, T3; for trip time with multi phase faults. According to the setting, the dedicated subroutine: Calculates the equations of the lines that define the nominal curve; Calculates the intersections between these lines and the corresponding angles; Given a line, that passes through the axis origin and is inclined of a certain angle referred to the R axis, calculates the intersections with the characteristic curve in terms of resistance and reactance: these are the nominal values that the test subroutine must compute. Relay Settings: R1 = 1.363 Ohms R1E = 10.613 Ohms X1 = 0.569 Ohms R2 = 1.468 Ohms R2E = 10.72 Ohms X2 = 1.09088 Ohms R3 = 1.8 Ohms R3E = 11.05 Ohms X3 = 2.764 Ohms Line Angle = 78 degree Inclination Angle = 78 degree RE/RL = 0.77 XE/XL = 3.01

Before the distance relay test start, output voltage and current are zero. When the program is started, three healthy voltages are applied for a second. After this, the program begins with the test of the general start (if requested); then the faults simulation begins to check the zone limits. Faults are generated as follows. Phase to ground fault: on the selected phase (AN, BN, CN) the voltage decreases while the current becomes the fault current; the voltages of the other two phases are modified. Two-phase fault on the pairs AB, BC, CA. With this selection: The amplitude and the angle of the voltages will be automatically modified to simulate a two-phase fault without ground. The two currents (IA & IB) are equal in module but opposite in phase. Three-phase fault: The three voltages have the same module, and also the three currents. After the relay tripping, the fault lasts for a programmable time (corresponding to the breaker opening delay) before returning to healthy conditions. Before starting with a new fault, healthy values are kept for a programmable time, to allow the reset of the relay under test.
