Page 20: Application Scope
Introduction 1.2 Application Scope Application Scope The 7VK61 breaker management relay is a multi-purpose starting and control device for automatic and manual closing of circuit breakers in electrical networks of all voltage levels. The automatic reclose function may be used on overhead lines for single-pole, three-pole or single- and three- pole automatic reclosure as well as multi-shot automatic reclosure.
Page 21 Introduction 1.2 Application Scope During a fault (system fault) important events and changes in conditions are saved in fault logs. Instantaneous fault values are also saved in the device and may be analyzed at a later time. Communication Serial interfaces are available for the communication with operating, control and memory systems. A 9-pin DSUB socket on the front panel is used for local communication with a personal computer.

Page 44: Automatic Reclosure Function (Optional)
Functions 2.2 Automatic reclosure function (optional) Automatic reclosure function (optional) Experience shows that about 85% of the arc faults on overhead lines are extinguished automatically after being tripped by the protection. The line can therefore be re-energized. Reclosure is performed by an auto- matic reclose function (AR).
Page 45 Functions 2.2 Automatic reclosure function (optional) Activation and deactivation The automatic reclosure function can be switched on and off by means of the parameter 3401 AUTO RECLOSE via the system interface (if available) and via binary inputs (if allocated). The switch states are saved internally (refer to Figure 2-6) and secured against loss of auxiliary supply.
Page 46 Functions 2.2 Automatic reclosure function (optional) Initiation Initiation of the automatic reclosure function means storing the first trip signal of a power system fault that was generated by a protection function which operates with the automatic reclosure function. In case of multiple reclosure, initiation therefore only takes place once, with the first trip command.
Page 47 Functions 2.2 Automatic reclosure function (optional) Example 3: 3 cycles are set. At least the first two cycles are set such that they can start the recloser. The action times are set as in example 1. The first protection trip takes place 0.5 s after starting. Since the action time for the 1st cycle has already expired at this time, it cannot start the automatic reclosure function, but the 2nd cycle, for which initiating is allowed, is activated immediately.
Page 48 Functions 2.2 Automatic reclosure function (optional) In the event of a single cycle reclosure this interrogation is usually sufficient. Since, for example, the air pres- sure or the spring tension for the circuit breaker mechanism drops after the trip, no further interrogation should take place.
Page 49 Functions 2.2 Automatic reclosure function (optional) The sequence above applies for single reclosure cycles. In 7VK61 multiple reclosure (up to 8 shots) is also possible (see below). Sequence of a 1-pole reclose cycle 1-pole reclose cycles are only possible if the external protection device and the Breaker Management Device 7VK61 relay are suitable for 1-pole tripping and if 1-pole tripping was enabled during configuration of the protection functions (address 110 Trip mode = 1-/3pole, see also Section 2.1.1.2 Setting...
Page 50 Functions 2.2 Automatic reclosure function (optional) Multiple reclosure If a short-circuit still exists after a reclosure attempt, further reclosure attempts can be made. Up to 8 reclosure attempts are possible with the automatic reclosure function integrated in the 7VK61. The first four reclosure cycles are independent of each other. Each one has separate action and dead times, can operate with 1- or 3-pole trip and can be blocked separately via binary inputs.
Page 51 Functions 2.2 Automatic reclosure function (optional) This no-voltage check on the line is of advantage if a small generator (e.g. wind generator) is connected along the line. Reduced Dead Time (RDT) If automatic reclosure function is performed in connection with time-graded protection, non-selective tripping before reclosure is often unavoidable in order to achieve fast, simultaneous tripping at all line ends.
Page 52 Functions 2.2 Automatic reclosure function (optional) In the illustrated example, the lines are disconnected at positions I, II and III. In I reclosure takes place after the configured dead time. At position III a reduced dead time can be used (see above) if there is also an infeed on busbar B.

Functions 2.2 Automatic reclosure function (optional) Setting Notes 2.2.2 General If the internal automatic reclosure function is to be used, the type of reclosure must be selected during the configuration of the functions (Section 2.1.1.2 Setting Notes) in address 133 Auto Reclose and in address 134 the AR control mode.
Page 59 Functions 2.2 Automatic reclosure function (optional) presupposes that a pickup signal of the external device is also connected to the 7VK61; otherwise an evolving fault can only be detected with the external trip command even if with with PICKUP was set here. The reaction in response to sequential faults can be selected at address 3407.
Page 60 Functions 2.2 Automatic reclosure function (optional) Dead line check / Reduced dead time Under 3431 the dead line check or the reduced dead time function can be activated. Either the one or the other can be used as the two options are contradictory. The voltage transformers must be connected to the line side of the circuit breaker if either of these modes is to be used.
Page 61 Functions 2.2 Automatic reclosure function (optional) ping is allowed, 1- pole tripping will be prevented during the reclaim time. Each fault is thus disconnected in three poles while the reclaim time is active. Address 3403 T-RECLAIM allows disabling the reclaim time in ADT mode. In doing so, the ADT cycle including its settings and release conditions is restarted after unsuccessful automatic reclosing.
Page 62 Functions 2.2 Automatic reclosure function (optional) 3457 1.AR Tdead3Trip is the dead time after 3-pole tripping. If you only want to allow a 1-pole reclose cycle, set the dead time for 3-pole tripping to ∞. If you only want to allow a 3-pole reclose cycle, set the dead time for 1-pole tripping to ∞, the protection then trips 3-pole for each fault type.

Page 76 Functions 2.3 Overcurrent protection (optional) short delay can be useful in case of long cables for which high inrush currents can be expected, or for trans- formers. This delay depends on the intensity and the duration of the transient overcurrents as well as on which stages were selected for the fast switch onto fault clearance.
Page 77 Functions 2.3 Overcurrent protection (optional) [formel-ueberstromzeit-hochstrom-3-oz-010802, 1, en_GB] If short-circuit currents exceed 2365 A (primary) or 19.7 A (secondary), there is a short circuit on the line to be protected. This fault can immediately be cleared by the time overcurrent protection. Note: the calculation was carried out with absolute values, which is sufficiently precise for overhead lines.
Page 78 Functions 2.3 Overcurrent protection (optional) The set times are mere additional delays for the independent stages, which do not include the inherent oper- ating time of the protection. If only the phase currents are to be monitored, set the pickup value of the earth fault stage to ∞.
