2 Overcurrent Protection / 7SJ600 Application Wide range of applications The SIPROTEC 7SJ600 is a numerical overcurrent relay which, in addition to its primary use in radial distribution networks and motor protection, can also be employed as backup for feeder, transformer and generator differential protection. The SIPROTEC 7SJ600 provides definite-time and inverse-time overcurrent protection along with overload and negative-sequence protection for a very comprehensive relay package. In this way, equipment such as motors can be protected against asymmetric and excessive loading. Asymmetric short-circuits with currents that can be smaller than the largest possible load currents or phase interruptions are reliably detected. The integrated control function allows simple control of a circuit-breaker or disconnector (electrically operated/motorized switch) via the integrated HMI, DIGSI 3 or DIGSI 4 ( 4.3) or SCADA (IEC protocol).

3 Overcurrent Protection / 7SJ600 Construction The relay contains all the components needed for Acquisition and evaluation of measured values Operation and display Output of signals and trip commands Input and evaluation of binary signals SCADA interface (RS48) Power supply. The rated CT currents applied to the SIPROTEC 7SJ600 can be 1 or A. This is selectable via a jumper inside the relay. Protection functions Definite-time characteristics The definite-time overcurrent function is based on phase-selective measurement of the three phase currents and/or earth current. Optionally, the earth (ground) current I E (Gnd) is calculated or measured from the three line currents I L1(I A), I L2(I B) and I L3(I C). The definite-time overcurrent protection for the 3 phase currents has a low-set overcurrent element (I>), a high-set overcurrent element (I>>) and a high-set instantaneous-tripping element (I>>>). Intentional trip delays can be parameterized from 0.00 to seconds for the low-set and high-set overcurrent elements. The instantaneous zone I>>> trips without any intentional delay. The definite-time overcurrent protection for the earth (ground) current has a low-set overcurrent element (I E>) and a high-set overcurrent element (I E>>). Intentional trip delays can be parameterized from 0.00 to seconds. Two different housings are available. The flush-mounting/cubicle-mounting version has terminals accessible from the rear. The surface-mounting version has terminals accessible from the front.

4 Overcurrent Protection / 7SJ600 Thermal overload protection (ANSI 49) Protection functions Thermal overload protection (ANSI 49) The thermal overload protection function provides tripping or alarming based on a thermal model calculated from phase currents. Thermal overload protection without preload For thermal overload protection without consideration of the preload current, the following tripping characteristic applies only when Fig. /24 Tripping characteristic of the negative-sequence protection function I 1.1 I L For different thermal time constants T L, the tripping time t is calculated in accordance with the following equation: 3 t = T 2 I 1 I L L I = Load current I 2 = Pickup current T L = Time multiplier The reset threshold is above I/I N Thermal overload protection with preload The thermal overload protection with consideration of preload current constantly updates the thermal model calculation regardless of the magnitude of the phase currents. The tripping time t is calculated in accordance with the following tripping characteristic (complete memory in accordance with IEC 602-8). 2 2 I I pre k I N k I N t = τ ln 2 I 1 k I N t = Tripping time after beginning of the thermal overload τ = 3. T L I pre = Pre-load current T L = Time multiplier I = Load current k = k factor (in accordance with IEC 602-8) ln = Natural logarithm = Rated (nominal) current I N Negative-sequence protection (I 2>>, I 2>/ANSI 46 Unbalanced-load protection) The negative-sequence protection (see Fig. /24) detects a phase failure or load unbalance due to network asymmetry. Interruptions, short-circuits or crossed connections to the current transformers are detected. Furthermore, low level single-phase and two-phase short-circuits (such as faults beyond a transformer) as well as phase interruptions can be detected. This function is especially useful for motors since negative sequence currents cause impermissible overheating of the rotor. In order to detect the unbalanced load, the ratio of negative phase-sequence current to rated current is evaluated. I 2 = Negative-sequence current T 12 = Tripping time Transformer protection The high-set element permits current coordination where the overcurrent element functions as a backup for the lower-level protection relays, and the overload function protects the transformer from thermal overload. Low-current single-phase faults on the low voltage side that result in negative phase-sequence current on the highvoltage side can be detected with the negative-sequence protection. Cold load pickup By means of a binary input which can be wired from a manual close contact, it is possible to switch the overcurrent pickup settings to less sensitive settings for a programmable duration of time. After the set time has expired, the pickup settings automatically return to their original setting. This can compensate for initial inrush when energizing a circuit without compromising the sensitivity of the overcurrent elements during steady state conditions. 3-pole multishot auto-reclosure (AR, ANSI 79) Auto-reclosure (AR) enables 3-phase auto-reclosing of a feeder which has previously been disconnected by timeovercurrent protection. Trip circuit supervision (ANSI 74TC) One or two binary inputs can be used for the trip circuit monitoring. Control The relay permits circuit-breakers to be opened and closed without command feedback. The circuit-breaker/disconnector may be controlled by DIGSI, or by the integrated HMI, or by the LSA/SCADA equipment connected to the interface. For further details please refer to part 2 Overview. /22

5 Overcurrent Protection / 7SJ600 Protection functions Switch-onto-fault protection If switched onto a fault, instantaneous tripping can be effected. If the internal control function is used (local or via serial interface), the manual closing function is available without any additional wiring. If the control switch is connected to a circuit-breaker bypassing the internal control function, manual detection using a binary input is implemented. Busbar protection (Reverse interlocking) Binary inputs can be used to block any of the six current stages. Parameters are assigned to decide whether the input circuit is to operate in open-circuit or closed-circuit mode. In this case, reverse interlocking provides high-speed busbar protection in radial or ring power systems that are opened at one point. The reverse interlocking principle is used, for example, in medium-voltage power systems and in switchgear for power plants, where a high-voltage system transformer feeds a busbar section with several medium-voltage outgoing feeders. Fig. /2 Reverse interlocking Motor protection For short-circuit protection, e.g. elements I>> (0) and I E (0N) are available. The stator is protected against thermal overload by ϑ s> (49), the rotor by I 2> (46), starting time supervision (48). Motor starting time supervision (ANSI 48) The start-up monitor protects the motor against excessively long starting. This can occur, for example, if the rotor is blocked, if excessive voltage drops occur when the motor is switched on or if excessive load torques occur. The tripping time depends on the current. Features Fig. /26 Wiring communication For convenient wiring of the RS48 bus, use bus cable system 7XV103 (see part 1 of this catalog). t TRIP = I t Istart rms 2 start max for I rms > I start, reset ratio I N I start approx t TRIP = Tripping time I start = Start-up current of the motor t start max = Maximum permissible starting time = Actual current flowing I rms Serial data transmission A PC can be connected to ease setup of the relay using the Windows-based program DIGSI which runs under MS-Windows. It can also be used to evaluate up to 8 oscillographic fault records, 8 fault logs and 1 event log containing up to 30 operational indications.
