Why residual current monitoring?

A comprehensive readiness for operation around the clock, constant competitive pressure and high cost pressure require the highest degree of electrical safety in the power supply of industrial, functional and residential buildings. With continuous monitoring of safety-relevant circuits for fault currents, residual currents and stray currents, incipient critical operating states are detected at an early stage. A potential risk of personal injury, fire damage and material damage as well as EMC interferences can thus be avoided.

The benefits at a glance:

• Preventive electrical safety for man and machine
• High availability of power supply systems
• Reducing EMC interferences
• Time and cost-optimised maintenance
• Significant reduction of operating costs and cost risks
• Saving potential thanks to periodic verification according to the German Social Accident Insurance (DGUV) regulation 3

Increased fire protection

• Detecting potential fire hazards caused by high fault currents as soon as they occur
• Signalling N conductor overload or interruption at an early stage
• Preventing material damage due to unintentional displacement of the star point caused by N conductor interruption
• Avoiding consequential costs resulting from material and ecological damage

Improved economic efficiency

• Reducing maintenance and operating expenses considerably
• Avoiding expensive and unplanned system downtimes through information at an early stage
• Higher productivity through increased operational reliability
• Saving of costs through lower insurance premiums
• Assistance for investment decision by detecting weak points in the electrical installation

Safe power supply – in all areas

The range of application of residual current monitors and systems extends from data centres, banks, insurances and office buildings, hospitals, traffic engineering to energy supply and distribution, broadcasting stations, communication technology systems and continuous production processes.
