Electrical safety devices to monitor, detect, locate, and interrupt ground faults in grounded, ungrounded, and high-resistance grounded systems.

Protection for people and equipment

• Insulation monitoring for variable speed drives
• Insulation monitoring devices for grounded and insulated AC and DC systems
• Insulation fault location for grounded and insulated systems
• Off-line monitoring
• Hospital test equipment
• Hospital insulation monitoring and change-over equipment
• Portable insulation test equipment

Advantages

• Reduced maintenance and repair costs by early indication of insulation faults
• Higher operational reliability – by alarm instead of power interruptions
• Improved protection and monitoring functions for extended systems with high capacity consumers
• Reducing fire risk
