The STL (Short-Circuit Testing Liaison) is an international forum for voluntary collaboration between testing organizations in the field of HV.

The objective of the STL is to harmonize the implementation of IEC and regional standards for type testing of HV electrical equipment.

The STL is interested in high-voltage transmission and distribution electrical equipment for which standardized tests such tests include short-circuit and dielectric.

ASEFA high power Laboratories dealing with high voltage equipment are associated within ESE. ESE is the French member of the STL.
