If not, they are reported only as ON.

Depending on the number of avail- able binary inputs not connected to a common potentialsupervision with one or two binary inputs can be se- lected. Motor Restart Inhibit 66 Functions 2. Products for Power Quality and Measurement go. Hard- ware adjustments to the power system data might be necessary. Reorganizing Frequent addition and deletion of objects creates memory areas that can no longer be used.

The reactance value X’ is entered as a reference value x’, i.

Should any of these setpoints be reached, exceeded or undershot during operation, the device issues a warning which is in- dicated in the form of an operational message.

There are tools for testing the system interface and the binary inputs and outputs of the device. CB ready monitoring window 79M Auto Recl. The action time is launched when pickup of any function is detected, which siemenx set as source of the automatic reclosure program.


Inverse Time Characteristic toc Functions 2. Default values which are sufficient in most cases are simeens. Mounting and Commissioning 3. They are marked with letters explained in the following table.

Up to 20 value pairs current, time may be entered. Oscillographic event recordings contain the maximum information on the be- havior of the protection. Directional Overcurrent Protection 67, 67n Functions 2. Page 31 Introduction 1. sismens

Double Activation Blockage Parallel switching operations are interlocked. This feature is used to verify control wiring from the device to plant equipment operational checks during commissioning.

Page 72 Functions 2. Following the general diagrams are diagrams that show siemes proper connections of the devices to primary equipment in many typical power system configurations.


High Speed Busbar Transfer xiemens. The blocking results in a current jump in the phases. The presetting of the jumpers corresponds to the configuration ordered. Page – Impacts on the Functionality of the Devi Here the delta address must be set to VT Connect. Function Logic Functions 2.


The user is also allowed to generate user-defined messages. Jumpers X to X must be set to the same position! Oscillographic records obtain the maximum information about the behaviour of the protection. Auxiliary Functions Functions 2. Page – Creating Oscillographic Recordings for T The same applies to 79 AR 50N-1 inst.


Search Search term s Search. The location and ratings of the miniature fuse F1 and of the buffer battery G1 are shown in the following figure.

SIPROTEC 7SJ62 – Digital Grid – Siemens

In addition, the measured values are also constantly monitored for plausibility, therefore, the current transformer and voltage transformer circuits are largely integrated into the monitoring. Furthermore, the measurement of all three phase-to-ground voltages is a requirement. Page 55 Functions 2. The user can create up to 20 flexible protection functions.

Page 90 Functions 2. The standard connection is A, B, C, Gnd. In 7dj62 example, the reference voltage transformers V are the ones of the transformer high side, i. If only two phase-to-phase voltages were measured, it would not be possible to evaluate two of the required criteria.
