Digital Fault Recorders & PMU
The fast, sure way to identify weaknesses
General Information
- Description
The quality of a power system depends on a multitude of parameters that are defined precisely in international standards. Digital Fault Recorders & PMU are recording devices designed to measure and document all these parameters on both the supplier and consumer side.
They offer numerous functions, including fault recorder, power and frequency recorder, system quality recorder, message printer, and network diagnosis system with fault locator.

SIMEAS R
Synchronization unit
- Description
- Ordering details
The Synchronisation Unit is used for conversion of different standard time systems and different output formats in a SIMEAS R and DAKON usable format. The advantage is that a time adaptation will be done automatically (also after a outage of the auxiliary power supply), where ever the system is installed. This is only possible with the Sync.-Box 7KE6000-8H_2_ (with decoder for a Hopf-signal), which is connected to a GPS Hopf receiver with a simulated DCF77 signal.
Time synchronization is achieved via a special input of the processor module to which a synchronization box (7KE6000-8HA*) is connected externally. Depending on implementation, the synchronization box can pick up the time signal from various receiver types, for example, via a GPS, DCF77 or IRIG-B. Synchronization with a GPS signal is the usual method. This requires special receivers that generally output a modulated telegram (DCF77, IRIG-B). This time telegram is passed on to the synchronization box. (In Germany and neighboring countries the DCF77 signal can be received directly. In this special case, the synchronization box can be connected to a DCF77 receiver with an integrated ferrite antenna.)
- Decoder for DCF 77 signal
- To conect to a GPS receiver with DCF77 output sigal (For example to a HOPF 6870 GPS Receiver)
- This is the best choice for all applications worldwide!
- Decoder for IRIG B signal (e.g. of GPS receiver)
- The IRIG B signal has the following disadvantages:
- the year is not indicated
- there is no switchover from summer to winter time
- there is no relative time (not orientated towards time zones)
- Decoder for demodulated DCF77 signal, Open Collector Connection
- Connection via serial port
- (Connection via terminals 11,12,13)
- Time Synchronization Unit
- In a housing with snap-on attachmentfor 35 mm top-hat rail according to DIN EN 500 022 with connection cable for SIMEAS R and DAKON PC.
- The control input 1 of CPU of SIMEAS R has to bedimensioned for 24 V DC to connect a time synchronization unit 7KE6000-8HA.
- While ordering the Cetral unit 7KE6000-XXXXX-BXXX,please make sure that B=1,5,6 OR 7, depending on the controlvoltage for the binary inputs.
