L & H Engineering has been successfully using the detection of corona (UV) to assess the health of energized components on power delivery and generation since 2000.

L & H Engineering has been routinely using “solar-blind” corona detection technology across the voltage spectrum used to

• find defective insulators of all types,
• identify defective disconnect switches,
• find defective bushings on transformers and breakers and
• assess the health of arrestors, potheads and the myriad other energized components that are used in our power systems.

With the “solar-blind” corona detection technology, L & H Engineering can identify

• damaged energized components,
• damaged polymer insulators (NCI),
• damaged porcelain insulators,
• damaged conductors,
• defects in new construction,
• deterioration due to design defects,
• track build-up of contamination,
• track aging of components as well as
• radio Interference and audible noise sources.

This detection technology also finds corona in power and control power cabinets as well as motors and generators.

The “solar blind” technology used by L & H Engineering makes detection of corona sources independent of ambient lighting conditions.

This corona technology is helping utilities avoid costly unscheduled outages and failures in substations, transmission lines and distribution lines as well as track level of contamination.
