Application Scenarios

This relay excels in environments where power system reliability is critical. A recent customer in the oil & gas sector deployed multiple units across their offshore platforms, reporting a 40% reduction in fault diagnosis time thanks to the module’s waveform capture capabilities. Common applications include:

• Substation feeder protection
• Industrial power distribution systems
• Smart grid implementations
• Renewable energy integration points

We frequently supply this model alongside other GE protection relays like the SR469-P5-HI-A20 and IS230SRTDH2A, often as part of complete system upgrades.
