About Electrodistribution Company

Facts About Elektro Gorenjska

Elektro Gorenjska is one of the largest Slovenian Electrodistribution Companies, which operates middle voltage (MV) as well as low voltage (LV) infrastructure. It owns 1.333 MV/LV transformer stations and 14 HV (high voltage)/LV transformer stations, mainly in the region of Gorenjska. Its' customer base consists of around 87.000 customers.

Elektro Gorenjska transformer stations were equipped with approximately 200 Iskra's measuring centres MI 7150, which were installed at the beginning of this millennium. They were equipped with serial communication RS 232. A few of them were also equipped with new types of Iskra instruments, namely with 18 MC 760 network analyzers and 25 MC 750 network recorders. For data transfer from transformer stations into the control centre, Elektro Gorenjska used WiMax, GPRS and Ethernet communication.

The management of Elektro Gorenjska wanted to have better insight into power quality related power grid parameters within transformer stations. For this reason we proposed equipping a majority of their MV/LV transformer stations with network analyzers MC 760, network recorders MC 750 and some power quality analyzers MC 774. Characteristics of our measuring devices are described below.

We also had to properly address the problem of data collection from transformer stations. For this purpose we introduced the MiSmart server for remote monitoring and collecting operational measurements from transformer stations. These recorder measurements were setup to include energy counters, powers, power factors, voltages, currents etc. Recorder evaluation periods were set at 1, 5 or 10 minutes meaning that all data was sent to the server immediately after evaluation and successful storage into the device recorder. Along with recorded measurements our system also provided real time alarm information to the electro-distribution company. This was setup by using alarms about voltage absence, overvoltage undervoltage, overcurrent andfrequency deviations.. Alarms also enable detection of overheating of interior of transformer stations or physical intrusion.
