SIEMENS 7KE85 Digital Fault Recorder - SIPROTEC 7KE85 Device with Expansion Module

Description

Powerful Fault Recorder with integrated measurement of synchrophasors (PMU) in accordance with IEEE C37.118 and power-quality measurement in accordance with IEC 61000-4-30. Due to the great flexibility of trigger functions, the SIPROTEC 7KE85 is ideally suited for monitoring the entire energy value added chain, from generation to distribution. The high-performance automation and flexible configuration with DIGSI 5 complements the range of functions.

Main function	Fault Recorder
Inputs and outputs	4 predefined standard variants with up to 40 analog

channels, 43 binary inputs, 33 binary outputs
Hardware flexibility| Flexibly adjustable and expandable I/O quantity structure within the scope of the SIPROTEC 5 modular system
Housing with| 1/3 to 1/1 x 19″

Applications

The fault recorder is for use in medium-voltage systems, highvoltage systems, and systems for very high voltage 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 supply quality
Dynamic behavior of generators
Closing and breaking operations of transformers (saturation response)
Power fluctuations and power-swing cycles
Test runs during commissioning

Functions

DIGSI 5 permits all functions to be configured and combined 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 in accordance with IEC 61000-4-30
