Measuring and Monitoring
Systems and equipment are becoming more and more complex, due to growing automation, rationalisation, and the increasing use of control electronics in machines. Required maintenance work is increasing, making it more difficult for humans to modify such systems. Not only the security, but also the service lives of such systems are highly important. Preventative maintenance which helps avoid malfunctions or reliably correct them in a short time helps to save costs. Using measurement and monitoring relays is becoming more and more economical, as lost production time is difficult to make up. You’ve faced the situation before: complex production systems, high demands for quality, delivery time, and delivery reliability, with permanent cost pressure. Today more than ever, these kinds of pressures require comprehensive operational readiness to maintain and even improve international competitiveness. In practice, however, comprehensive operational readiness is often difficult to achieve; ageing, moisture, contamination, mechanical damage, and other factors can lead to creeping insulation failures. Such undiscovered issues can lead to cost-intensive system and operational standstills, repair costs, and typically high follow-up costs due to production shutdowns. In the worst case scenario, insulation failures can even be a frequent cause of fires and personal injuries.Measuring and monitoring limit values for electrical variables
