The voltage to be evaluated is selected in Power System Data 1 see Chapter 2. Table Of Contents Contents 4. Figure Indications prior to editing Clicking the texts allows for editing short text and long text as required by the application Figure In the current path, the I current is valid, when the transformer neutral current is connected to the device.
This is why such faults are not detected at all or not selectively by the ordinary time overcurrent protection. Processing of interlocking conditions for switching e.
All elements are independent from each other and can be com- bined as desired. Transformer Differential Protection go. Glossary Double command Double commands are process outputs which indicate 4 process states at 2 outputs: Checking System Connections Mounting and Commissioning 3. Operating Panel On Device Date And Time Stamping It shows the setting possibilities for each function in maximum configuration.
By pressing ‘print’ button you will print only current page. This is recognized as soon as the threshold value of the circuit breaker position detection 7sj662 BkrClosed I MIN is exceeded in at least one phase.
Communication branch A communications branch corresponds to the configuration of 1 to n users which communicate by means of a common bus. Due to the variety of application options and the available system configurations, it is not possible to make a detailed mamual of the necessary tests.
Test For High Impedance Protection Standard Interlocking checks are provided for each individual control command. Determination of Direction Moreover, the following data apply to direction determination: Tighten all terminal screws, including those that are not used.
Warning of dangerous voltages when operating an electrical device Non-observance of the following measures can result in death, personal injury or substantial property damage. Tools Digital Grid Digital Grid. Jumpers X to X must be set to the same position!

Mechanical Stress Tests The automatic reclosing system can be programmed in such manner that any of the elements of Table can initiate Starts 79not initiate No influenceor block reclosing Stops Power System Data 1 Hardware Modifications Mounting and Commissioning 3.
The settings 7sn62 correspond with the old parameters and are specified as follows. Follow mankal procedure described in this section, whenever hardware modifica- tions are carried out.
Types Of Commands Functions 2. The blocking signal is not lifted unless the rotor temperature has fallen below the mannual limit, that is, when exactly one start becomes possible without exceeding the excessive rotor temperature limit. Synchronization Function Functions 2. Under address L-sections FL the number of line section must be selected, which is required for the accurate description of the line. The following relationship exists between the primary and the secondary power: The input amplifier IA element provides a high-resistance termination for the input quantities.

If only the definite time elements are desired, the address 46 should be set to Definite Time. Commands that are initiated internally command processing in the CFC are not subject to switching authority and are therefore always “allowed”. The binary input message must be deactivated again within this time in order to start the dead time.
Both the previous history of an overload and the heat loss to the environment are taken into account. Table shows the assignment of the evaluated loops to the possible pickup scenarios of the protection el- ements. Disassembly Mounting and Commissioning 3. Busbar Tripping For testing the distribution of the trip commands in the substation in the case of breaker failures it is important to check that the trip commands to the adjacent circuit breakers is correct.
