Measurement technology for efficient systems

High energy efficiency makes a significant contribution to reducing operational costs, minimizes environmental impact and helps to comply with ever stricter legal regulations, such as the Energy Efficiency Act.

By implementing a modern energy management system, companies can monitor and analyze their energy consumption in detail in order to identify and improve inefficient processes. The early detection of deviations in energy consumption enables improved performance analysis of the machines for reliable energy efficiency reports and the monitoring of specific energy indicators for efficiency optimization. The data can be seamlessly incorporated into an energy management system in accordance with standards such as ISO 50001 or environmental management.

Janitza offers measurement technology for the data acquisition of electrical energy and the corresponding software to process and analyze data from energy sources such as electricity, gas and compressed air as well as other process media such as water, nitrogen, etc. in accordance with standards. Further information can be found in Energy management. By recording all energy sources and auxiliary materials, CO₂ emissions from energy can be visualized and used as the basis for achieving sustainability targets. As suppliers, smaller companies are also affected by such requirements Further information can be found in “On the path towards a CO₂ balance.”

High-performing load management allows energy flows to be controlled intelligently. This means that companies can reduce their load peaks and as a result also their energy costs, save resources, and guarantee the stability of their own mains supply.

The ability to control the electrical loads prevents overloading and ensures an even distribution. Predictive peak load reduction achieved through targeted consumer control can significantly reduce grid connection costs. Energy distribution systems can be utilized more efficiently as fewer reserves are required, which also saves costs.

In addition, the use of renewable energies is optimally supported by load management, for example in distributing and controlling self-generated energy for charging electric vehicles or the use of an energy storage system. The aim is for the company to consume a large proportion of the energy generated in its own grid. This reduces energy costs for the network operator and makes the use of renewable energy such as photovoltaics more efficient and more profitable.

Security of supply is essential in many industrial areas, as even momentary interruptions or faults in the power supply can result in high costs and damage to systems.

The power quality must be monitored in compliance with standards to ensure a secure supply. The continuous monitoring of power quality and analysis of compensation currents also enables companies to assess the state of machines and systems. Unscheduled maintenance or production downtimes are avoided thanks to the early detection of leakage currents or load changes. Detailed records are used to analyze the power quality, schedule maintenance and ensure compliance with relevant standards such as DIN EN 61000-2-4 as well as to document and analyze negative changes and improvements in the energy supply.

The functionality of production facilities can be monitored and logged using a comprehensive residual current monitoring system.

Fires and failures can be detected and prevented before they occur, therefore ensuring operational security. Effective troubleshooting leads to shorter downtimes and improved availability of the power supply. This helps to minimize unscheduled stoppages and production downtimes. Manual isolation testing in accordance with DGUV V3 can be avoided thanks to constant monitoring if certain requirements are met; the remaining part of the test in accordance with DGUV V3 can be carried out without a break in production while the systems are in operation. Costs are reduced and production downtimes are avoided without risking the safety of machines and systems.
