Technical Architecture & Functional Positioning

The F650-G-N-A-B-F-2-G-1-HI-C-E is the top-specification variant in the F650 family when a large, intuitive color graphical interface is required at the bay level. The “G” front panel provides operator-focused visualization (mimic diagrams, trending, alarm banners) that reduces training time and improves situational awareness in utility and large industrial substations.

Internally, it uses the same proven dual-DSP architecture as other F650 models, but allocates additional processing capacity to real-time screen refresh and FlexLogic execution. The basic I/O board “B” combined with redundant Ethernet makes this exact configuration the preferred choice for indoor switchgear where local control and annunciation are prioritized over extensive hard-wired I/O.

Typical Application Scenarios

• Main incoming feeder protection and control in 11–33 kV indoor distribution substations with operator HMI requirements
• Industrial plant primary MV switchboard bay controller with local mimic display and manual control capability
• Ring-main unit automation with graphical single-line overview and pushbutton breaker operation
• Replacement of legacy static or first-generation digital relays while adding modern graphical interface and IEC 61850 MMS reporting
• Campus or hospital critical power distribution requiring clear local status indication and reduced operator error

 

Quality Standards & Testing Procedures

Each F650-G-N-A-B-F-2-G-1-HI-C-E undergoes an extended graphical-interface acceptance suite in addition to standard protection testing.

Standardized Testing Protocol (SOP)

Visual & HMI Verification Pixel defect check on color LCD, backlight uniformity, pushbutton tactility, and LED color sequencing test.

72-Hour Burn-In Continuous operation at +65 °C with cyclic display page rotation and alarm simulation.

Protection & Automation Verification

• Full secondary injection of all enabled elements using Omicron/Doble test sets
• FlexLogic sequence testing with simulated inputs and verification of output timing
• Graphical mimic navigation and control action validation (open/close commands via pushbuttons)

Communication & IEC 61850 Testing

• Complete MMS, GOOSE publish/subscribe, and buffered/unbuffered reporting
• Redundant Ethernet port failover verification (<4 ms recovery)

Final Documentation Delivered with printed test report, EnerVista setting file, factory default graphical screens, and serialized conformance certificate.
