  • Page 22: Overall Operation

    Introduction 1.1 Overall Operation Overall Operation This chapter introduces the SIPROTEC Feeder Protection and Recloser Controller 7SC80 and gives an overview of the device's application, properties and functions. Analog Inputs The measuring inputs (MI) convert the currents and voltages coming from the transformers and adapt them to the level appropriate for the internal processing of the device.
  • Page 23 1.1 Overall Operation [7sc80-hw-struktur-20110520, 1, en_US] Figure 1-1 Hardware structure Feeder Protection and Recloser Controller 7SC80 Microcomputer System Apart from processing the measured values, the microcomputer system (μC) also executes the actual protec- tion and control functions. They especially include: •...
  • Page 24 The HMI of the device is used to connect the operator panel. The operator panel can be permanently attached to the 7SC80 or it can be detached. The operator panel contains 32 LEDs for displaying operating states or indications and a 6-line field for displaying operational indications and measured values or on the Web Monitor a graphical field for displaying the control display.

  • Page 25: Application Scope

    1.2 Application Scope Application Scope The Feeder Protection and Recloser Controller 7SC80 can be used to protect, control, and monitor the line protection in networks with grounded, low-resistance grounded, isolated, or compensated neutral. It is suit- able for radial networks supplied from a single source, open or closed looped networks, and for lines with sources at both ends.
  • Page 26 Alternatively, additional connection options are available with serial DNP3.0 RS485 protocols. If an EN100 module is available, you can use the protocols DNP3 TCP, IEC61850, IEC 60870-5-104, or PROFINET. Further- more, connecting a SICAM I/O unit is possible via IEC61850 GOOSE.

  • Page 27: Characteristics

    Their pickup values and time delays can be set independently of these elements. • For inverse time overcurrent protection, it is possible to select from various characteristics of different standards or define user-specific characteristics SIPROTEC Compact, 7SC80, Manual E50417-G1140-C486-A8, Edition 07.2017...
  • Page 28 • Monitoring of falling below (f<) and/or exceeding (f>) with 4 frequency limits and time delays that are independently adjustable • Insensitive to harmonics and abrupt phase angle changes • Adjustable undervoltage threshold. SIPROTEC Compact, 7SC80, Manual E50417-G1140-C486-A8, Edition 07.2017...
  • Page 29 Sectionalizer • Have no capacity to break the fault current • Isolate the fault current sections of a distribution circuit only when an upstream breaker or recloser has interrupted the fault current. SIPROTEC Compact, 7SC80, Manual E50417-G1140-C486-A8, Edition 07.2017...

    The available protection functions and additional functions can be configured as Enabled or Disabled. For some functions, there is a choice between several alternatives possible, as described below. Functions configured as Disabled are not processed in the 7SC80, there are no indications and the associ- ated setting parameters (functions, limiting values) are not available.

In particular, they must have the same transformer ratios and approximately identical knee-point voltage With 7SC80, the high-impedance principle is particularly suited for detecting ground faults at transformers, generators, motors and parallel reactors in grounded systems. Figure 2-42 on the left shows an application example for a grounded transformer winding or a grounded generator.
