GE IC3600SGDE1A Ground Detector Card

Product Brief Description

GE IC3600SGDE1A is a thermocouple ground detector card for the Speedtronic Mark I and Mark II turbine control systems. It is installed inside the thermocouple processing module, equipped with four independent ground detection circuits, used to monitor ground leakage faults of control and protection thermocouple channels. It triggers fault alarm when the thermocouple leakage resistance falls between 12kΩ and 36kΩ, protecting the turbine temperature measurement loop from ground failure.

Product Functions

• Four independent ground detection circuits for thermocouple monitoring
• One channel for control thermocouple ground leakage detection
• Two channels for protection thermocouple A and B channel supervision
• One spare channel for optional third protection thermocouple
• Detect thermocouple leakage to ground within 12kΩ–36kΩ resistance range
• Send ground fault alarm signal to the main turbine control logic
• Prevent invalid temperature readings caused by thermocouple short to ground
• PCB conformal coating for stable operation in power plant turbine cabinets

Application Scenarios

• Legacy GE Speedtronic Mark I and Mark II gas/steam turbine control cabinets
• Power plant turbine thermocouple temperature measurement protection loops
• Captive power plants, refineries and chemical industry turbine units
• Old turbine control system overhaul, spare replacement and retrofit
• Combustion temperature monitoring and protection for heavy-duty gas turbines
• Industrial power generation equipment predictive maintenance and spare stocking
