Transient Surge Analysis Services

What is Transient Surge Analysis?

Transient Surge Analysis involves evaluating electrical systems for sudden, short-duration voltage spikes caused by lightning strikes, switching operations, or fault conditions. These surges can damage sensitive equipment, reduce insulation life, and cause system downtime.

Elion’s Transient Surge Analysis services help industries identify surge risks, simulate transient events, and recommend protection measures to enhance system reliability and safety.

Why is Transient Surge Analysis Important?

  • Protects sensitive equipment from voltage spikes and insulation failure.
  • Prevents unplanned downtime due to surge-related faults.
  • Improves system reliability and life expectancy of electrical assets.
  • Supports compliance with IS/IEC and IEEE standards for surge protection.
  • Helps design effective surge protection systems for your facility.
  • Enhances safety by reducing arc flash and fault risks.

What Causes Transient Surges?

  • Lightning strikes near or on the facility
  • Switching operations of large inductive loads
  • Fault clearing in the system
  • Capacitor bank switching
  • Load rejection and sudden energization
  • Electrostatic discharge (ESD)
