    Introduction The device family SIPROTEC 7SJ62/64 devices is introduced in this section. An overview of the devices is presented in their application, characteristics, and scope of functions. Overall Operation Application Scope Characteristics SIPROTEC 4, 7SJ62/64, Manual C53000-G1140-C207-8, Edition 08.2016...

  • Page 20: Overall Operation

    The 4 voltage transformers of 7SJ623, 7SJ624, 7SJ625, 7SJ626 and 7SJ64 can either be applied for the input of 3 phase-to-ground voltages, one displacement voltage V or a further voltage for the synchronization func- tion. SIPROTEC 4, 7SJ62/64, Manual C53000-G1140-C207-8, Edition 08.2016...

  • Page 22 The operator or service interface allows you to operate the device from a remote location or on site using a standard browser. This is possible during commissioning, checking and also during operation of the devices. The SIPROTEC 4 Standard “WEBMonitor” is available for this task. Power Supply A power supply unit (Vaux or PS) delivers power to the functional units using the different voltage levels.

  • Page 23: Application Scope

    1.2 Application Scope Application Scope The numerical SIPROTEC 4 7SJ62/64 multifunction protection relays are versatile devices designed for protec- tion, control and monitoring of busbar feeders. The devices can be used for line protection in networks that are grounded, low-resistance grounded, isolated, or of a compensated neutral point structure. They are suited for networks that are radial or looped, and for lines with single or multi-terminal feeds.
  • Page 24 A 9-pole DSUB miniature female connector on the front panel serves the purpose of local communication with a PC. By means of the SIPROTEC 4 operating software DIGSI, all operational and evaluation tasks can be executed via this operator interface, such as specifying and modifying configuration parameters and settings, configuring user-specific logic functions, retrieving operational messages and measured values, inquiring device conditions and measured values, issuing control commands.

    Combination devices are bay devices with protection functions and a control display. Combination matrix From DIGSI V4.6 onward, up to 32 compatible SIPROTEC 4 devices can communicate with one another in an Inter Relay Communication combination (IRC combination). Which device exchanges which information is defined with the help of the combination matrix.

  • Page 726 (energy purchase/supply, energy transportation). MLFB MLFB is the abbreviation for "MaschinenLesbare FabrikateBezeichnung" (machine-readable product designa- tion). This is the equivalent of an order number. The type and version of a SIPROTEC 4 device is coded in the order number. Modem connection This object type contains information on both partners of a modem connection, the local modem and the remote modem.
  • Page 727 Each object has properties. These might be general properties that are common to several objects. An object can also have specific properties. Off-line In offline mode a connection to a SIPROTEC 4 device is not required. You work with data which are stored in files. On-line When working in online mode, there is a physical connection to a SIPROTEC 4 device.

PROFIBUS address Within a PROFIBUS network a unique PROFIBUS address has to be assigned to each SIPROTEC 4 device. A total of 254 PROFIBUS addresses are available for each PROFIBUS network.
  • Page 729 SIPROTEC 4 Variant This object type represents a variant of an object of type SIPROTEC 4 device. The device data of this variant may well differ from the device data of the original object. However, all variants derived from the original object have the same VD address as the original object.
  • Page 730 Users From DIGSI V4.6 onward , up to 32 compatible SIPROTEC 4 devices can communicate with one another in an Inter Relay Communication combination. The individual participating devices are called users. A VD (Virtual Device) includes all communication objects and their properties and states that are used by a communication user through services.
