As a part of energy efficiency improvement program, at the end of September, 2014 flexible electronic fiber-optical current transformers (FEFOCT) were installed on Irkutsk aluminium smelter (JSC IrkAZ) to measure direct current in aluminium pot rooms, transfer and save data.
IrkAZ is a subsidiary company of JSC “RusAL”, it is one of oldest aluminium smelters in East Siberia.
In 2013, specialists of Profotech already installed a set of FEFOCT that is currently being operated in aluminium pot rooms of JSC “IrkAZ”.
The main reason to apply Profotech equipment in power-consuming industry is that it can provide the following advantages:
- wide dynamic current and temperature range of sensitive element (-60+60 degrees)
- compact size and light weight;
- easy to install (no need to precisely position a sensitive element about a bus)
- high accuracy of measurements (FEFOCT is put on the State Register of Measuring Instruments). Can operate under very dusty conditions.
Installation supervision and start-up and adjustment operations were performed by specialists of Profotech.
