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
Central unit ZE8/16 with integrated ethernet port
- Description
- Functional overview
The SIMEAS R is used as a digital recorder to acquire and analyze power processes. Due to its flexibility, the SIMEAS R can be used as a fault recorder, a paperless recorder, and to record the power quality.
It is used for quality assurance in power stations, and extra-high, high-voltage and medium-voltage installations. SIMEAS R records power faults and power quality and monitors the secondary and primary technical facilities.
