For both devices, the currents and voltages involved as well as phase shifts between the local and remote measured quantities can be displayed.

Page Remote Measured Values Functions 2. Page Oscillographic Fault Records Functions 2. Fault recording is running 2. They can be called up at the front of the device, read out via the operating interface using a PC with DIGSI, or trans- ferred to a central master station via the system interface.

Page Control Authorization Functions 2. Page Command Processing Functions 2. Additionally, user-defined interlocking con- ditions can be configured separately for each device. Page Interlocking Functions 2. An overview for processing the interlocking conditions in the relay is shown in Figure The are marked by letters as explained in Table Page Process Data Functions 2. These indications contain information on the cause. With the corresponding allocation configuration these indications are entered in the event log, thus serving as a report.

Page Mounting And Commissioning Mounting and Commissioning This chapter is primarily intended for experienced commissioning engineers.

The commissioning engineer must be familiar with the commissioning of protection and control systems, with the management of power systems and with the relevant safety rules and guidelines.

Under certain circumstances adaptations of the hardware to the particular power system data may be necessary. Warning of improper transport, storage, installation, and application of the device. Non-observance can result in death, personal injury or substantial property damage. Trouble free and safe use of this device depends on proper transport, storage, installation, and application of the device according to the warnings in this instruction manual.

Page Mounting and Commissioning 3. The preset allocation can be found in the tables in Section A. The pick-up threshold of the binary inputs must therefore be substantially below half the rated control DC volt- age.

Page Hardware Modifications Mounting and Commissioning 3. Follow the procedure described in this section, whenever hardware modifications are carried out. Page Disassembly Mounting and Commissioning 3. This activity does not apply if the device is for surface mounting. The jumpers X60 to X64 must all be set to the same rated current, i. Page Interface Modules Mounting and Commissioning 3.

Interface modules for devices with surface mounting housing must be retrofitted in our manufacturing centre. No hardware modifications are required to use it. Termination Bus-capable interfaces always require a termination at the last device on the bus, i.

Page Reassembly Mounting and Commissioning 3. The mounting locations are shown in figure For the model of the device designed for surface mounting, use the metal lever to insert the C-CPU-2 board. The installa- tion is easier with the lever. The ordering codes are stated in Appendix, Section A. Page Panel Mounting Mounting and Commissioning 3. For dimensions see the Technical Data in Section 4.

Page Checking Connections Mounting and Commissioning 3. The position of the connectors is depicted in the fol- lowing figures. The visual check of the assignment of the transmission and reception channels is of particular importance.

With RS and fibre optic interfaces, each connection is dedicated to one transmission direction. Table D-subminiature connector assignment of the time synchronization interface Pin No. Warning of Laser rays Warning of dangerous voltages Non-observance of the following measures can result in death, personal injury or substantial property damage. Therefore, only qualified people who are familiar with and adhere to the safety procedures and precautionary measures shall perform the inspection steps.

This can be done using secondary test equipment or other test equipment for checking continuity. Make sure that terminal continuity is not wrongly simulated in reverse direction via current transformers or their short-circuiters. Page Commissioning Mounting and Commissioning 3. 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. Only qualified people shall work on and around this device.

They must be thoroughly familiar with all warnings and safety notices in this instruction manual as well as with the applicable safety steps, safety regulations, and precautionary measures. This feature is used to verify control wiring from the device to plant equipment operational checks during commissioning.

Before executing the first change of the operating state the password No. To do this, the dialog box must be updated. You can either connect the PC to the device locally using the operator interface at the front, or the service in- terface at the back of the PC Figure Now the devices communicate by them- selves. This requires a personal computer with web browser. Figure shows the general information of the communication topology.

Figure Communication topology — Depending on the device version and the setting of the breaker failure protection, 1-pole or 3-pole trip are possible. Any direction is possible but must be known. Hazardous voltages during interruptions in secondary circuits of current transformers Non-observance of the following measure will result in death, severe personal injury or substantial property damage.

Short-circuit the current transformer secondary circuits before current connections to the device are opened. An earth current 3I of the approximately same level as I occurs. Accordingly, the voltage is missing and a zero sequence voltage 3U appears. Again check the polarity and set it right after short- circuiting all the three current transformers.

Any special function or logic added to the device must be checked. A general procedure cannot in the nature of things be specified.

Oscillograhpic records provide the maximum information about the behaviour of the protection relay. All the plug connectors must be correctly inserted. Do not apply force! The tightening torques must not be exceeded as the threads and terminal chambers may otherwise be dam- aged!

The setting values should be checked again if they were changed during the tests. The electrical and functional data of fully equipped devices are followed by the mechanical data, with dimensional drawings. Page General Technical Data 4. Page Auxiliary Voltage Technical Data 4.

Bay controllers Bay controllers are devices with control and monitoring functions without protective functions. Bit pattern indication Bit pattern indication is a processing function by means of which items of digital process information applying across several inputs can be detected together in parallel and processed further.

Which device exchanges which information is defined with the help of the combination matrix. Communication branch A communications branch corresponds to the configuration of 1 to n users that communicate by means of a common bus. They serve for direct information exchange among the relays.

This mechanism implements cross-communication between bay units. Global Positioning System. Satellites with atomic clocks on board orbit the earth twice a day on different paths in approx. The objective of this standard is the interoperability of devices from different manufacturers on the station bus.

An Ethernet network is used for data transfer. Initialization string An initialization string comprises a range of modem-specific commands. These are transmitted to the modem within the framework of modem initialization. Page Glossary Limit value Limit value, user-defined Master Masters may send data to other users and request data from other users. DIGSI operates as a master. Metered value Metered values are a processing function with which the total number of discrete similar events counting pulses is determined for a period, usually as an integrated value.

Page Glossary Navigation pane The left pane of the project window displays the names and symbols of all containers of a project in the form of a folder tree. Object properties Each object has properties. Project Content-wise, a project is the image of a real power supply system.

Graphically, a project is represented as a number of objects which are integrated in a hierarchical structure. The software is a modular system with basic and optional packages.
