Southeast Asia Power Grid Solutions: Resilient Electronic Voltage Transformers for Extreme Environments
Southeast Asia Market Pain Points & EVT Solutions
Pain Points |
EVT Solutions |
High Temperature & Humidity |
IP67 Protection + Silicone Potting: Withstands 40°C/95% RH environments, increasing lifespan by 50%. |
Frequent Grid Fluctuations |
Class 0.2 Accuracy + Wide Input Range (110kV-500kV): Adapts to unstable grids. |
Difficult Island Deployment |
Modular Design (<20kg/unit): Enables helicopter airlifting, reducing remote area installation costs. |
Combustible Traditional Transformers |
Dry-Type Solid-State Design: Eliminates fire risk (Certified to IEC 61869-11). |
Smart Grid Integration Needs |
Digital Output (IEC 61850-9-2LE): Seamless integration with SCADA/EMS. |
