MarsGen-61850
Project status: Research & Development
Purpose
Testing and calibration of electrical energy meters, PQ analyzers and phasor measurement units (PMU) with 61850-9-2LE outputs.
Synthesis of IEC 61850-9-2 data streams in compliance with all timing, continuity and UTC synchronization requirements for packet data transmission.
Description
Marsgen-61850 comes as a single unit in an IP67 enclosure. The following connectors are installed under a hermetically sealed cover:
- Ethernet for connection to a PC which synthesizes digital streams and controls the whole instrument;
- Digital stream output for connection to a SFR adapter;
- Frequency inputs/outputs (BNC) for synchronization with an external source;
MarsGen-61850 is controlled from an external control terminal (PC) by the specialized software.
