Insulation monitoring

Application

For increased operating safety and reliability of electrical installations: unearthed power supply systems (IT systems)

Increased operating safety, personal protection and reliability of electrical installations are very important factors for everyone in charge of an electrical installation. In addition, there are the requirements for time and cost saving maintenance and repair for both simple control circuits and complex power supplies in industrial plants and in buildings.

IT systems – for advance information

Unearthed power supplies (IT systems) monitored by an A-ISOMETER^® provide solutions which on the one hand offer comprehensive protection of people and equipment and on the other hand meet the ever-increasing high requirements for availability and cost reduction.

Improved economic efficiency

Expensive and unexpected interruptions to operation are avoided
Time and costs for maintenance are reduced
Weak points in the installation are recognized
Investment management is supported

Increased operating reliability

No interruption to operation in the event of phase-to-earth fault
No control malfunction in the event of insulation faults
Electrical installations are kept at a high level of availability
Off-line monitoring

Optimised maintenance

Insulation deteriorations are early recognized and signalle
Automatic localisation of sections of the system with insulation faults
Optimised planning of time and personnel resources
Central information about the condition of the electrical installation
Remote diagnosis via Internet/Ethernet

Increased fire prevention

Gradually developing insulation faults are detected at an early stage
Arcing faults, a frequent cause of fire, do not occur
Areas subject to explosion and fire hazards can be separated from the rest of the system by means of isolating transformers and can be monitored
