Market Access and Compliance: Certification of Insulators, Bushings, and Surge Arresters

In the ever-evolving landscape of electrical power systems, the reliability and safety of infrastructure depend heavily on the performance of critical components such as insulators, bushings, and surge arresters. These elements play a vital role in ensuring uninterrupted power delivery, protecting equipment from electrical faults, and maintaining system stability under diverse environmental and operational conditions.

At KEMA Labs, we ensure the highest level of quality and reliability for insulators, bushings, and surge arresters through a comprehensive suite of testing services, adherence to international standards, and globally recognized certification deliverables.

Testing Capabilities

Our laboratories are equipped to perform a wide range of tests tailored to the specific characteristics and operational demands of each component:

  • Electrical and Dielectric Tests : Evaluate insulation properties and voltage endurance.
  • Mechanical Tests : Assess structural integrity and mechanical strength.

Environmental and Ageing Tests : Simulate real-world conditions such as temperature fluctuations, humidity, pollution, and salt fog exposure.

  • Power Arc and Short Circuit Tests : Validate resilience against electrical arcs and extreme fault currents (up to 80 kA).
  • Routine and Type Tests : Ensure consistent quality across production batches and verify design performance.
  • Special and Customized Tests : Developed to meet unique customer specifications or emerging regulatory needs.

Applicable Standards

All testing is conducted in accordance with globally recognized standards, including but not limited to:

  • IEC 60099-4 ,  IEEE C62.11  – Surge arresters
  • IEC 60273 ,  IEC 60137 ,  IEC 61462 ,  IEC 60383 ,  IEC 62217  – Insulators and bushings
  • IEEE C57.19.00 ,  ANSI C29  – Transformer bushings and insulators

These standards define the technical requirements, classifications, and acceptance criteria necessary for safe and efficient operation in modern power systems.

Deliverables and Certification

Following testing and inspection, KEMA Labs provides a full suite of documentation to support product validation and market access:

  • Type test Reports  and  Design Verification Reports
  • Certificates of Compliance  and  Certificates of Conformity
  • Inspection Reports  and  Short Circuit Performance Certificates
  • Homogeneous Series Certification  for product families

These deliverables are internationally recognized by manufacturers, utilities, and regulatory bodies, helping to streamline procurement, ensure regulatory compliance, and support global trade.
