Does constant availability go without saying? The solution is simple: You know the situation: complex production systems, high requirements in terms of the quality, delivery time and reliability, permanent cost pressure. This requires more than ever a comprehensive operational readiness in order to be able to maintain and improve the competitiveness at the international level. In practice, however, a comprehensive operational readiness is often given only conditionally, because insulation faults may slowly but progressively occur due to ageing, moisture, pollution, mechanical damage and...

Functioning principle of a residual current monitor (RCM) Residual current monitoring device, also known as RCM (Residual Current Monitor), measures and monitors the residual and fault currents in earthed systems (TN, TT systems). They are used in systems in which a message should be sent in event of an error, but the system should not be switched off. Disturbances resulting from insulation faults will therefore not lead to any unwanted operational downtime, damage to components and higher costs. Difference to the residual current circuit breaker: Residual current circuit breaker, so-called...

Insulation monitoring VARIMETER IMD Functional principle of the insulation monitoring device (IMD) Insulation monitoring device (abbreviated: IMD), monitors the insulation resistance in non-earthed systems (IT systems). DIN VDE 0100-410 and DIN VDE 0100-710 standards mandate the use of an insulation monitoring device in non-earthed systems, in order to detect a first occurring fault between an active conductor and a component or against the ground. The IMD has to emit an optical and / or acoustic signal if a first fault occurs. Disturbances which are the result of insulation faults and...

Insulation fault detection system VARIMETER EDS Functioning principle of an insulation fault detection system (EDS) The insulation fault detection system of the VARIMETER EDS family (Earth-Fault Detection System), which consists of the test current transformer RR 5886 and the insulation fault detection device RR 5887, will automatically localise the fault source. The reliability of the systems can be improved by using nonearthed power supply systems (IT systems), since the onepole direct connection of the power supply to the ground remains maintained and the system can continue with its...
