At SEN EDS, we offer expert Electrical Insulation Coordination Analysis services across Andhra Pradesh to safeguard high-voltage systems from transient overvoltages caused by lightning, switching operations, or faults. Our advanced studies enhance system reliability, reduce equipment failure, and ensure full compliance with IEC 60071 and IEEE standards.

We support power utilities, industrial plants, substations, and renewable energy developers with detailed analysis for both AIS and GIS installations—up to 400kV.

Insulation Coordination is the strategic alignment of equipment insulation ratings with surge protection devices. It ensures your system can withstand unexpected overvoltages and operate safely and efficiently over time.

Our Core Analysis Services

  • Switching Transient Study
    Simulates events like transformer energization or breaker operations to identify insulation stress.
  • Lightning Impulse Analysis
    Evaluates system response to lightning-induced surges to protect critical equipment.
  • Surge Arrester Selection & Placement
    Ensures optimal positioning and rating of surge arresters for maximum protection.
  • Fault Transient Assessment
    Analyzes how insulation behaves during internal faults, improving fault tolerance.
  • Standards-Based Compliance
    All studies comply with IEC 60071, IEEE, and national electrical codes.
