Based on long term experience from over 100,000 density switch installations, GDC was developed to match HV manufacturer demands for quality, reliability and cost.
APPLICATIONS
High Voltage Circuit Breakers
Circuit Switchers
GIS Substations
Gas insulated High Voltage Bushing
GIL sections
BASIC FUNCTIONS
Visual indication of density level
Uses reference chamber principle ultimate stability and repeatability
Up to four independent contacts with decreasing or increasing thresholds
FEATURES & BENEFITS
Able to follow the Isochor even in liquid phase of SF6, that means no false alarm in low temperature
Ability to calibrate a Self-diagnosis contact to check leakage in reference volume.
No contact bouncing
Shock proof
Designed for outdoor installation
Maintenance free
Available with continuous monitoring analog output signal for remote monitoring and totalization of fugitive SF6 emissions and SF6 refill maintenance forecasting.
