To provide better insight into energy consumption, Iskra installed electrical measuring instruments at various points in Kovis Livarna's factory. This included 44 low-end instruments and 5 high-end network recorders to monitor energy use, power quality, and other metrics. Wireless devices were also used to measure consumption from large machines and compressed air. This new system allows Kovis Livarna to remotely monitor consumption data in real-time, better analyze equipment performance, and improve energy management.

About Kovis Livarna d.o.o.
Situation before the intrduction of our system
The tradition of the foundry goes back to 1968. In the 90s, we
produced castings under the name of Livarna Štore. Since 1996, the
foundry has been wholly owned by Anton Pangrčič and has been an
independent legal entity with the name Kovis Livarna, d.o.o., since
1999. In its history, Kovis Livarna, d.o.o., has faced many challenges in
thebusinessenvironment.

Because of a lack of power quality and consumption information there were big challenges to face before the introduction of our system. Kovis
Livarna didn't have any information about energy consumption of different machines. It was almost impossible to determine the amount of
consumed energy within the factory in relation to a particular large consumer (machine). They had difficulties composing energy consumption
annual reports for regulator (IEC standardization) purposes. Supervision and determination of energy leakages from different sources like gas,
water, compressed air or electricity within the factory was also very difficult. Prediction of energy consumption was complicated, because no

To be more cost effective the management of Kovis Livarna wanted to have better insight into energy consumption of the factory. For this
reason we proposed an installation of Iskra electrical measuring instruments at different measuring points within the factory. Instruments
wereplacedatstrategicbigenergyconsumptionlocationsthroughoutthefactory(electricfurnaces,robots,cranesetc.)aswellasinthecentral
transformer station. We installed 44 low-end instruments (20 MC 330 and 24 MC 350). For communication we used the serial/Ethernet
converter MI 488 device, which enables MODBUS polling of relevant data registers from the before mentioned instruments. We also collected
measurements from 5 ethernet-enabled MC 750 network recorders. All measuring instruments monitor: energy, active power, reactive power,
currents, voltages and phase angles. For measuring of electrical energy consumption of crucial large consumers we distributed 23 energy
meters (MC 330 and WS 1302) throughout the factory. Via pulse outputs they were connected to low power radio C2 wireless devices (868 MHz)
for sending data into C100 wireless communication receivers. Through C100 energy consumption data is then sent via Ethernet, into a
centralized dedicated MiSmart server which is located within the company's LAN. We also equipped all measuring equipment with current
transformers to do required current measurements. One of the C2 communication devices has been connected via pulse inputs (through a
PLC)intoanaircompressorinordertomeasureconsumptionofcompressedair.

MC 750 C2 C100MC 350 MC 750 C2 C100MC 350
With our system the customer now gets remote and centralized key electrical parameter data for monitoring of energy, active power, reactive
power, currents, voltages, phase angles with special emphasis on electrical energy and reagent (gass, water, compressed air) consumption.
Key decision makers are now able to receive real-time information on the operation of installed equipment and are also able to respond,
without delay, to possible failures. They can make operational and strategic decisions based on failure analysis. The system also enables
better supervision over energy losses within the factory as well as better and faster maintenance planning according to historic data. The
system architecture is modular and so easily extendable to other locations and measurement points. Also a quick Excel data export capability
isavailableforregulatorreportingwhichenablesthecustomertohaveenergyconsumptionreportsreadyafterafewclicks.
