Why Integrate Master Meter Data
Into The SCADA System?
• Track Distribution System Flows In Realtime.
• Bulk Customer Billing & Automatic Reports.
• Detect and Zone Transmission Line Leaks.
• Increase Employee Safety.
• Improve Data Accuracy.
• Leverage Already-Existing SCADA System Infrastructure.
The Bottom Line: Reduce Operational Costs
