If no measuring voltage is connected to this input, this subsection is irrelevant.

Page of Go. Furthermore, specific thresholds and settings of the select- ed function group seimens checked. This means that the line can be connected again. Page 85 Functions 2. The selection is made via parameter setting of the automatic reclosing function.

Double Activation Blockage Parallel switching operations are interlocked. Page 84 Functions 2. Temperature Stage 2 Pickup With these quantities ground active power and ground reactive power is calculated. Ground Fault Protection 64, 67n s50n s51n s Functions 2. Figure Example for the generation of a manual close signal using siemenx internal control function Note For an interaction between the automatic reclosing function 79 AR and the control function, an extended CFC logic is necessary.

Overvoltage Protection 59 Functions 2. Based on the following information, it can also be determined which of the provided functions should be used. Two-phase Time Overcurrent Protection Protection Operating Quantities The two-phase overcurrent protection functionality is used in grounded or compensated systems where inter- action of three-phase devices with existing two-phase protection siemenx is required. The protection function represents a thermal replica of the equipment to be protected overload 77sj62 tion with memory capability.


The presetting of the jumpers corresponds to the configuration ordered. Siemens recommends that all devices be installed such that they are not exposed to direct sunlight, nor subject to 7wj62 fluctuations in temperature that may cause condensation to occur.

Tripping is thus not possible. Therefore, tripping can be time-graded depending on how severe voltage collapses are. For details see also in- formation at margin heading “Interaction isemens the Automatic Reclosing Function” Page 61 Functions 2.

System Connections Action Time Checking: For the latter setting, only two phase— phase voltages or only the displacement voltage V can be connected. In order that the minimum voltage for controlling the binary input is ensured, R is derived as: In general, to optimize the operation of the inputs, the pick- up voltage of the inputs should be set to most closely match the actual control voltage being used. Page 44 Functions 2.


If set to Alarm Only, tripping is not possible and only a ground fault log is generated. Page Glossary Metered value Metered values are a processing function with which the total number of discrete 7sj26 events counting pulses is determined for a period, usually as an integrated value.

High-set current elements and overcurrent element always operate with a definite tripping time, the third element TOC operates with an inverse tripping time.

They are, therefore, not enabled — and no pickup or tripping of these protective functions will occur.

Page 60 Functions 2. The logic diagram on the mode of operation in an isolated system is illustrated in Figure Table Of Contents Contents 2. Control commands can originate from four command sources: Communication Interfaces Technical Data 4. Grounding Grounding is the total of all means and measured used for grounding. To do so, the dialog 7s6j2 Hardware Test must be opened again to view the physical state of the binary 7wj62.

When setting the Power System Data 1 see Section 2. Page 45 Functions 2. This section provides ordering information for the models of this device. The same applies to 79AR 51N instantaneous. The measurement values can be called via the navigation bar.
