Iskra helped global foundry company to get better insight into energy consumption by installation of Iskra electrical measuring instruments at strategic big energy consumption locations (electric furnaces, robots, cranes) and in the central transformer station.

1. Power Quality Management
CASE STUDY
Instruments remote monitoring

2. Foundry company that provides castings for customers from
various industries:
 the manufacture of railway vehicles
 machine building
 the production of agricultural machinery
 the production of construction machinery
 the production of pumps, fittings and valves
 castings for construction
FACTS ABOUT THE COMPANY
Case Study

3. SITUATION BEFORE THE INTRODUCTION OF OUR SYSTEM
 Lack of power quality and consumption information
 No information about energy consumption of different
machines.
 Impossible to determine the amount of consumed energy
within the factory in relation to a particular large consumer
(machine).
 Difficulties composing energy consumption annual reports
for regulator (IEC standardization) purposes.
 Difficulties with supervision and determination of energy
leakages from different sources like gas, water,
compressed air or electricity within the factory.
 Difficulties with prediction of energy consumption (no power
profile historic data was available).
 No means to centrally monitor their large energy
consumers.

4. OUR SOLUTION – BETTER INSIGHT INTO ENERGY CONSUMPTION
Case Study
 Installation of Iskra electrical measuring instruments at strategic big energy consumption locations (electric
furnaces, robots, cranes etc.) and in the central transformer station.
44 Low-end Instruments (20 MC 330 and 24 MC 350).
Serial/Ethernet converter MI 488 device, which enables MODBUS polling of relevant data registers from 44 low-end
instruments
5 ethernet-enabled MC 750 network recorders
23 energy meters (MC 330 and WS 1302) for measuring energy consumption of large consumers. 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. All measuring instruments monitor: energy, active power, reactive power, currents,
voltages & phase angles.

6. Business case
Key user benefits
 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.
 Real-time information on the operation of installed equipment, momental respond, without delay, to possible
failures.
 Failure analysis for better operational and strategic decisions
 Better supervision over energy losses within the factory as well as better & faster maintenance planning
according to historic data.
 The system architecture is modular and so easily extendable to other locations and measurement points.
 Quick Excel data export capability for regulator reporting which enables the customer to have energy
consumption reports ready after a few clicks.
