Fault Recorder

DIGSI 5 permits all functions to be configured and com-bined as required.

• Up to 40 analog channels

• Fast-Scan Recorder

• Up to 2 slow-scan recorders

• Up to 5 continuous recorders and 2 trend recorders

• Power quality recordings according to IEC 61000-4-30 (harmonics, THD, TDD - in preparation)

• Sequence-of-events recorder for continuous recording of binary status changes and IEC 61850 GOOSE messages

• Usable as Phasor Measurement Unit (PMU) according to IEEE C37.118 protocol

• Transmission of the records and triggering via IEC 61850 GOOSE messages

• Variable sampling frequencies parameterizable between 1 kHz and 16 kHz

• Distribution of the mass storage of 16 GB to the various recorders by the user as desired

• Intelligent monitoring routines of the storage medium ensure a high level of availability and completeness for the archived data

• Lossless data compression

• Time synchronization via Precision Time Protocol (PTP) IEEE 1588 protocol, IRIG-B, DCF77, and SNTP

• Routing of the measured values to the individual recorders as desired

• Combination of the measuring groups for the power calculation as desired

• Quality attributes for representing the instantaneous signal quality in the time signal view

• Trigger functions of a function block are fundamental component value, RMS value, zero-sequence, positive-sequence, negative-sequence system power, frequency power, Σ active power and Σ reactive power

• Level trigger and gradient trigger for every trigger function

• Flexible cross trigger and system trigger, manual trigger

• Creation of independent trigger functions with the graphic automation editor CFC (continuous function Chart)

• Trigger functions via a combination of single-point, doublepoint indications, analog values, binary signals, Boolean signals and GOOSE messages

• Consistent monitoring concept

• Auxiliary functions for easy tests and commissioning

• Special test mode for commissioning

• Integrated electrical Ethernet RJ45 for DIGSI 5 and IEC 61850 (reporting and GOOSE)

• Redundancy protocols PRP and HSR

• Cyber security to NERC CIP and BDWE Whitepaper requirements

• Up to 4 pluggable communication modules usable for
  different and redundant protocols

• Intelligent terminal technology enables prewiring and a simple device replacement

The fault recorder is for use in medium, high and extra-high voltage systems and in power plants with comprehensive trigger and recording functions. With the SIPROTEC 7KE85 fault recorder, you receive a clearly organized and event-related evaluation and documentation of your power system processes. You are thereby able to analyze failures in a targeted manner and optimize your power system.

Typical processes to be monitored and documented:

• System incidents, such as critical load cases or short circuits

• Failures of the quality of supply

• Dynamic behavior of generators

• Closing and breaking operations of transformers (saturation Response)

• Power fluctuations and power-swing cycles

• Test runs during commissioning

• Clearly organized documentation and focused analysis of power system processes and failures

• Data security and transparency over the entire lifecycle of the plant save time and money

• Purposeful and simple operation of the devices and software thanks to user-friendly design

• Increased reliability and quality of the engineering process

• Powerful communication components ensure safe and effective solutions

• Full compatibility between IEC 61850 Editions 1 and 2

• Highly available Ethernet communication due to integrated Ethernet redundancy protocols PRP and HSR
