Line trap and air core reactor testing

Line trap and air core reactor testing

DNV GL offers short circuit testing and certification of line traps and air core reactors, according to IEC 60353 and IEC 60076-6 standards

In many parts of the world signals such as phone data are transmitted over the power transmission network. Line traps are an important component to prevent these signals streaming in unwanted directions. However to supply this market, it is increasingly important to provide proof of quality and conformity to international standards.

Testing and certification gives you the necessary evidence. KEMA Type Test Certificates are recognized worldwide, opening the way to market opportunities.

Tests available
Our laboratories conduct testing and certification of both line traps and air core reactors. They can handle today’s high inductance value reactors, and are equipped to deliver very high amounts of power for short circuit testing.

The range of tests for line traps includes:

  • short circuit
  • dielectric
  • routine
  • discharge current
  • temperature rise tests

All are performed in accordance with international standard IEC 60353.

For reactors, we cover all types – air core, neutral and current limiting – with testing conducted according to the IEC 60076-6 standard.

You can opt for testing which leads to a KEMA Type Test Certificate. Such certification confirms that your components fully meet international standards.

Alternatively, we can provide you with a Report of Short-Time Current Performance or an Inspection Report. These describe the tests conducted and their results, but are not evidence that a component meets a certain standard or specification.

World-class facilities

Depending on the ratings, your products can be tested in our High-Voltage and High-Power Laboratories in Arnhem, the Netherlands or in Chalfont, Pennsylvania, USA.

Both facilities have the capacity to generate large amounts of short circuit power and can perform rigorous tests while minimizing the risk of damage to components. We use high-speed camera recording to observe the behaviour of reactors during short-time current tests.

A typical test set-up involves connecting a tuning device in parallel with the main coil. This simulates the attenuation and high frequency impedance characteristics of the power line.
