REPORT: Electric Power Grids of Russia - 2013

Since the UpGrid forum started, many experts were quick to "bury" the exhibition "Electrical Grids of Russia" - the event participation in which is a longterm tradition for electric power engineers all over Russia. We had the feeling that UPGrid - it's more for "white collars", while LEP (as is often simply referred to) - is the place where you meet designers, maitenance engineeres, including specialists from different parts of Russia - those who work directly with the equipment on the ground. And, you know, our assumption looks true. "Digital Substation" prepared a special report from the eve

Free PTPv2 implementation

Open-source world is rich with interesting projects. Today we present a project which offers a possibility of PTP implementation for further studies. Project is called PTPd (PTP daemon) and it offers implementation of the Precision Time protocol (PTP) as defined by the relevant IEEE 1588 standard. PTP Version 2 implements IEEE-1588-2008.

SICAM IO Unit 7XV5673

Recently we have received binary signals input/output module by Siemens - SICAM IO UNIT 7XV5673. This device is absolutely new: as binary inputs/outputs expansion module it was presented last fall and, regarding to Siemens office, we were one of the first to try it out.

MAC-address — what is this?

In any packet transmitted over Ethernet there are two MAC-addresses present: one is a source MAC-address and another is a destination MAC-address. When forwarding data, Ethernet-switches use this important data. So what is a MAC-address? What are the differences between unicast, multicast and broadcast destination MAC-addresses? What destination MAC-addresses are common for IEC 61850 standard protocols? Let's have a more detailed look on this.
